+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+
+ Copyright (C) 1991 Free Software Foundation, Inc.
+ 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL.  It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it.  You can use it for
+your libraries, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if
+you distribute copies of the library, or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library.  If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, so that any problems introduced by others will not reflect on
+the original authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software.  To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+  Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License, which was designed for utility programs.  This
+license, the GNU Library General Public License, applies to certain
+designated libraries.  This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+  The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it.  Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program.  However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+  Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries.  We
+concluded that weaker conditions might promote sharing better.
+
+  However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves.  This Library General Public License is intended to
+permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them.  (We have not seen how to achieve
+this as regards changes in header files, but we have achieved it as regards
+changes in the actual functions of the Library.)  The hope is that this
+will lead to faster development of free libraries.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, while the latter only
+works together with the library.
+
+  Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+		  GNU LIBRARY GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library which
+contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Library
+General Public License (also called "this License").  Each licensee is
+addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also compile or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    c) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    d) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the source code distributed need not include anything that is normally
+distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Library General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+     Appendix: How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Library General Public
+    License as published by the Free Software Foundation; either
+    version 2 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Library General Public License for more details.
+
+    You should have received a copy of the GNU Library General Public
+    License along with this library; if not, write to the Free
+    Software Foundation, Inc., 59 Temple Place - Suite 330, Boston,
+    MA 02111-1307, USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
+
+  <signature of Ty Coon>, 1 April 1990

+# See librx/configure.in in the libg++ distribution for an example of how
+# to handle autoconf'd libraries.
+#
+# Things are complicated because 6 separate cases must be handled:
+# 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6.
+#
+# srcdir=. is special.  It must handle make programs that don't handle VPATH.
+# To implement this, a symlink tree is built for each library and for each
+# multilib subdir.
+#
+# The build tree is layed out as
+#
+# ./
+#   libg++
+#   newlib
+#   m68020/
+#          libg++
+#          newlib
+#          m68881/
+#                 libg++
+#                 newlib
+#
+# The nice feature about this arrangement is that inter-library references
+# in the build tree work without having to care where you are.  Note that
+# inter-library references also work in the source tree because symlink trees
+# are built when srcdir=.
+#
+# Unfortunately, trying to access the libraries in the build tree requires
+# the user to manually choose which library to use as GCC won't be able to
+# find the right one.  This is viewed as the lesser of two evils.
+#
+# Configure variables:
+# ${with_target_subdir} = "." for native, or ${target_alias} for cross.
+# Set by top level Makefile.
+# ${with_multisrctop} = how many levels of multilibs there are in the source
+# tree.  It exists to handle the case of configuring in the source tree:
+# ${srcdir} is not constant.
+# ${with_multisubdir} = name of multilib subdirectory (eg: m68020/m68881).
+#
+# Makefile variables:
+# MULTISRCTOP = number of multilib levels in source tree (+1 if cross)
+# (FIXME: note that this is different than ${with_multisrctop}.  Check out.).
+# MULTIBUILDTOP = number of multilib levels in build tree
+# MULTIDIRS = list of multilib subdirs (eg: m68000 m68020 ...)
+# (only defined in each library's main Makefile).
+# MULTISUBDIR = installed subdirectory name with leading '/' (eg: /m68000)
+# (only defined in each multilib subdir).
+
+# FIXME: Multilib is currently disabled by default for everything other than
+# newlib.  It is up to each target to turn on multilib support for the other
+# libraries as desired.

@@ -0,0 +1,23 @@
+This directory contains MPW scripts and related files that are needed to
+build Cygnus GNU tools for MPW.  The scripts should be somewhere on the
+command path; our usual practice has been to have a separate directory
+for the scripts, and put the tools (byacc, flex, and sed at least) there
+also; then it's easier to drag the support bits around as a group, or to
+upgrade MPW versions.  The complete package of scripts and tool binaries
+is usually available as pub/mac/buildtools.cpt.hqx on ftp.cygnus.com.
+
+"tr-7to8-src" is actually the source to an MPW script that transforms
+sequences like "\Option-d" into the actual 8-bit chars that MPW needs.
+It's only the source because it can't itself include any 8-bit chars.
+It *can* be processed into a genuine "tr-7to8" by using itself:
+
+	tr-7to8 tr-7to8-src | sed -e 's/Src//' >new-tr-7to8
+
+Use this to verify:
+
+	compare tr-7to8 new-tr-7to8
+
+If you don't have a working tr-7to8, then you will have to manually
+replace all occurrences of "\Option-d" with real Option-d (which looks
+like a delta), then do similarly with all the other "\Option-..."
+strings, and then change "\SrcOption-d" into the string "\Option-d".

+
+@node Makefile Basics
+@section General Conventions for Makefiles
+
+Every Makefile should contain this line:
+
+@example
+SHELL = /bin/sh
+@end example
+
+@noindent
+to avoid trouble on systems where the @code{SHELL} variable might be
+inherited from the environment.  (This is never a problem with GNU
+@code{make}.)
+
+Different @code{make} programs have incompatible suffix lists and
+implicit rules, and this sometimes creates confusion or misbehavior.  So
+it is a good idea to set the suffix list explicitly using only the
+suffixes you need in the particular Makefile, like this:
+
+@example
+.SUFFIXES:
+.SUFFIXES: .c .o
+@end example
+
+@noindent
+The first line clears out the suffix list, the second introduces all
+suffixes which may be subject to implicit rules in this Makefile.
+
+Don't assume that @file{.} is in the path for command execution.  When
+you need to run programs that are a part of your package during the
+make, please make sure that it uses @file{./} if the program is built as
+part of the make or @file{$(srcdir)/} if the file is an unchanging part
+of the source code.  Without one of these prefixes, the current search
+path is used.
+
+The distinction between @file{./} (the @dfn{build directory}) and
+@file{$(srcdir)/} (the @dfn{source directory}) is important because
+users can build in a separate directory using the @samp{--srcdir} option
+to @file{configure}.  A rule of the form:
+
+@smallexample
+foo.1 : foo.man sedscript
+        sed -e sedscript foo.man > foo.1
+@end smallexample
+
+@noindent
+will fail when the build directory is not the source directory, because
+@file{foo.man} and @file{sedscript} are in the source directory.
+
+When using GNU @code{make}, relying on @samp{VPATH} to find the source
+file will work in the case where there is a single dependency file,
+since the @code{make} automatic variable @samp{$<} will represent the
+source file wherever it is.  (Many versions of @code{make} set @samp{$<}
+only in implicit rules.)  A Makefile target like
+
+@smallexample
+foo.o : bar.c
+        $(CC) -I. -I$(srcdir) $(CFLAGS) -c bar.c -o foo.o
+@end smallexample
+
+@noindent
+should instead be written as
+
+@smallexample
+foo.o : bar.c
+        $(CC) -I. -I$(srcdir) $(CFLAGS) -c $< -o $@@
+@end smallexample
+
+@noindent
+in order to allow @samp{VPATH} to work correctly.  When the target has
+multiple dependencies, using an explicit @samp{$(srcdir)} is the easiest
+way to make the rule work well.  For example, the target above for
+@file{foo.1} is best written as:
+
+@smallexample
+foo.1 : foo.man sedscript
+        sed -e $(srcdir)/sedscript $(srcdir)/foo.man > $@@
+@end smallexample
+
+GNU distributions usually contain some files which are not source
+files---for example, Info files, and the output from Autoconf, Automake,
+Bison or Flex.  Since these files normally appear in the source
+directory, they should always appear in the source directory, not in the
+build directory.  So Makefile rules to update them should put the
+updated files in the source directory.
+
+However, if a file does not appear in the distribution, then the
+Makefile should not put it in the source directory, because building a
+program in ordinary circumstances should not modify the source directory
+in any way.
+
+Try to make the build and installation targets, at least (and all their
+subtargets) work correctly with a parallel @code{make}.
+
+@node Utilities in Makefiles
+@section Utilities in Makefiles
+
+Write the Makefile commands (and any shell scripts, such as
+@code{configure}) to run in @code{sh}, not in @code{csh}.  Don't use any
+special features of @code{ksh} or @code{bash}.
+
+The @code{configure} script and the Makefile rules for building and
+installation should not use any utilities directly except these:
+
+@c dd find
+@c gunzip gzip md5sum
+@c mkfifo mknod tee uname 
+
+@example
+cat cmp cp diff echo egrep expr false grep install-info
+ln ls mkdir mv pwd rm rmdir sed sleep sort tar test touch true
+@end example
+
+The compression program @code{gzip} can be used in the @code{dist} rule.
+
+Stick to the generally supported options for these programs.  For
+example, don't use @samp{mkdir -p}, convenient as it may be, because
+most systems don't support it.
+
+It is a good idea to avoid creating symbolic links in makefiles, since a
+few systems don't support them.
+
+The Makefile rules for building and installation can also use compilers
+and related programs, but should do so via @code{make} variables so that the
+user can substitute alternatives.  Here are some of the programs we
+mean:
+
+@example
+ar bison cc flex install ld ldconfig lex
+make makeinfo ranlib texi2dvi yacc
+@end example
+
+Use the following @code{make} variables to run those programs:
+
+@example
+$(AR) $(BISON) $(CC) $(FLEX) $(INSTALL) $(LD) $(LDCONFIG) $(LEX)
+$(MAKE) $(MAKEINFO) $(RANLIB) $(TEXI2DVI) $(YACC)
+@end example
+
+When you use @code{ranlib} or @code{ldconfig}, you should make sure
+nothing bad happens if the system does not have the program in question.
+Arrange to ignore an error from that command, and print a message before
+the command to tell the user that failure of this command does not mean
+a problem.  (The Autoconf @samp{AC_PROG_RANLIB} macro can help with
+this.)
+
+If you use symbolic links, you should implement a fallback for systems
+that don't have symbolic links.
+
+Additional utilities that can be used via Make variables are:
+
+@example
+chgrp chmod chown mknod
+@end example
+
+It is ok to use other utilities in Makefile portions (or scripts)
+intended only for particular systems where you know those utilities
+exist.
+
+@node Command Variables
+@section Variables for Specifying Commands
+
+Makefiles should provide variables for overriding certain commands, options,
+and so on.
+
+In particular, you should run most utility programs via variables.
+Thus, if you use Bison, have a variable named @code{BISON} whose default
+value is set with @samp{BISON = bison}, and refer to it with
+@code{$(BISON)} whenever you need to use Bison.
+
+File management utilities such as @code{ln}, @code{rm}, @code{mv}, and
+so on, need not be referred to through variables in this way, since users
+don't need to replace them with other programs.
+
+Each program-name variable should come with an options variable that is
+used to supply options to the program.  Append @samp{FLAGS} to the
+program-name variable name to get the options variable name---for
+example, @code{BISONFLAGS}.  (The names @code{CFLAGS} for the C
+compiler, @code{YFLAGS} for yacc, and @code{LFLAGS} for lex, are
+exceptions to this rule, but we keep them because they are standard.)
+Use @code{CPPFLAGS} in any compilation command that runs the
+preprocessor, and use @code{LDFLAGS} in any compilation command that
+does linking as well as in any direct use of @code{ld}.
+
+If there are C compiler options that @emph{must} be used for proper
+compilation of certain files, do not include them in @code{CFLAGS}.
+Users expect to be able to specify @code{CFLAGS} freely themselves.
+Instead, arrange to pass the necessary options to the C compiler
+independently of @code{CFLAGS}, by writing them explicitly in the
+compilation commands or by defining an implicit rule, like this:
+
+@smallexample
+CFLAGS = -g
+ALL_CFLAGS = -I. $(CFLAGS)
+.c.o:
+        $(CC) -c $(CPPFLAGS) $(ALL_CFLAGS) $<
+@end smallexample
+
+Do include the @samp{-g} option in @code{CFLAGS}, because that is not
+@emph{required} for proper compilation.  You can consider it a default
+that is only recommended.  If the package is set up so that it is
+compiled with GCC by default, then you might as well include @samp{-O}
+in the default value of @code{CFLAGS} as well.
+
+Put @code{CFLAGS} last in the compilation command, after other variables
+containing compiler options, so the user can use @code{CFLAGS} to
+override the others.
+
+@code{CFLAGS} should be used in every invocation of the C compiler,
+both those which do compilation and those which do linking.
+
+Every Makefile should define the variable @code{INSTALL}, which is the
+basic command for installing a file into the system.
+
+Every Makefile should also define the variables @code{INSTALL_PROGRAM}
+and @code{INSTALL_DATA}.  (The default for @code{INSTALL_PROGRAM} should
+be @code{$(INSTALL)}; the default for @code{INSTALL_DATA} should be
+@code{$@{INSTALL@} -m 644}.)  Then it should use those variables as the
+commands for actual installation, for executables and nonexecutables
+respectively.  Use these variables as follows:
+
+@example
+$(INSTALL_PROGRAM) foo $(bindir)/foo
+$(INSTALL_DATA) libfoo.a $(libdir)/libfoo.a
+@end example
+
+Optionally, you may prepend the value of @code{DESTDIR} to the target
+filename.  Doing this allows the installer to create a snapshot of the
+installation to be copied onto the real target filesystem later.  Do not
+set the value of @code{DESTDIR} in your Makefile, and do not include it
+in any installed files.  With support for @code{DESTDIR}, the above
+examples become:
+
+@example
+$(INSTALL_PROGRAM) foo $(DESTDIR)$(bindir)/foo
+$(INSTALL_DATA) libfoo.a $(DESTDIR)$(libdir)/libfoo.a
+@end example
+
+@noindent
+Always use a file name, not a directory name, as the second argument of
+the installation commands.  Use a separate command for each file to be
+installed.
+
+@node Directory Variables
+@section Variables for Installation Directories
+
+Installation directories should always be named by variables, so it is
+easy to install in a nonstandard place.  The standard names for these
+variables are described below.  They are based on a standard filesystem
+layout; variants of it are used in SVR4, 4.4BSD, GNU/Linux, Ultrix v4,
+and other modern operating systems.
+
+These two variables set the root for the installation.  All the other
+installation directories should be subdirectories of one of these two,
+and nothing should be directly installed into these two directories.
+
+@table @code
+@item prefix
+@vindex prefix
+A prefix used in constructing the default values of the variables listed
+below.  The default value of @code{prefix} should be @file{/usr/local}.
+When building the complete GNU system, the prefix will be empty and
+@file{/usr} will be a symbolic link to @file{/}.
+(If you are using Autoconf, write it as @samp{@@prefix@@}.)
+
+Running @samp{make install} with a different value of @code{prefix} from
+the one used to build the program should @emph{not} recompile the
+program.
+
+@item exec_prefix
+@vindex exec_prefix
+A prefix used in constructing the default values of some of the
+variables listed below.  The default value of @code{exec_prefix} should
+be @code{$(prefix)}.
+(If you are using Autoconf, write it as @samp{@@exec_prefix@@}.)
+
+Generally, @code{$(exec_prefix)} is used for directories that contain
+machine-specific files (such as executables and subroutine libraries),
+while @code{$(prefix)} is used directly for other directories.
+
+Running @samp{make install} with a different value of @code{exec_prefix}
+from the one used to build the program should @emph{not} recompile the
+program.
+@end table
+
+Executable programs are installed in one of the following directories.
+
+@table @code
+@item bindir
+@vindex bindir
+The directory for installing executable programs that users can run.
+This should normally be @file{/usr/local/bin}, but write it as
+@file{$(exec_prefix)/bin}.
+(If you are using Autoconf, write it as @samp{@@bindir@@}.)
+
+@item sbindir
+@vindex sbindir
+The directory for installing executable programs that can be run from
+the shell, but are only generally useful to system administrators.  This
+should normally be @file{/usr/local/sbin}, but write it as
+@file{$(exec_prefix)/sbin}.
+(If you are using Autoconf, write it as @samp{@@sbindir@@}.)
+
+@item libexecdir
+@vindex libexecdir
+@comment This paragraph adjusted to avoid overfull hbox --roland 5jul94
+The directory for installing executable programs to be run by other
+programs rather than by users.  This directory should normally be
+@file{/usr/local/libexec}, but write it as @file{$(exec_prefix)/libexec}.
+(If you are using Autoconf, write it as @samp{@@libexecdir@@}.)
+@end table
+
+Data files used by the program during its execution are divided into
+categories in two ways.
+
+@itemize @bullet
+@item
+Some files are normally modified by programs; others are never normally
+modified (though users may edit some of these).
+
+@item
+Some files are architecture-independent and can be shared by all
+machines at a site; some are architecture-dependent and can be shared
+only by machines of the same kind and operating system; others may never
+be shared between two machines.
+@end itemize
+
+This makes for six different possibilities.  However, we want to
+discourage the use of architecture-dependent files, aside from object
+files and libraries.  It is much cleaner to make other data files
+architecture-independent, and it is generally not hard.
+
+Therefore, here are the variables Makefiles should use to specify
+directories:
+
+@table @samp
+@item datadir
+The directory for installing read-only architecture independent data
+files.  This should normally be @file{/usr/local/share}, but write it as
+@file{$(prefix)/share}.
+(If you are using Autoconf, write it as @samp{@@datadir@@}.)
+As a special exception, see @file{$(infodir)}
+and @file{$(includedir)} below.
+
+@item sysconfdir
+The directory for installing read-only data files that pertain to a
+single machine--that is to say, files for configuring a host.  Mailer
+and network configuration files, @file{/etc/passwd}, and so forth belong
+here.  All the files in this directory should be ordinary ASCII text
+files.  This directory should normally be @file{/usr/local/etc}, but
+write it as @file{$(prefix)/etc}.
+(If you are using Autoconf, write it as @samp{@@sysconfdir@@}.)
+
+Do not install executables here in this directory (they probably belong
+in @file{$(libexecdir)} or @file{$(sbindir)}).  Also do not install
+files that are modified in the normal course of their use (programs
+whose purpose is to change the configuration of the system excluded).
+Those probably belong in @file{$(localstatedir)}.
+
+@item sharedstatedir
+The directory for installing architecture-independent data files which
+the programs modify while they run.  This should normally be
+@file{/usr/local/com}, but write it as @file{$(prefix)/com}.
+(If you are using Autoconf, write it as @samp{@@sharedstatedir@@}.)
+
+@item localstatedir
+The directory for installing data files which the programs modify while
+they run, and that pertain to one specific machine.  Users should never
+need to modify files in this directory to configure the package's
+operation; put such configuration information in separate files that go
+in @file{$(datadir)} or @file{$(sysconfdir)}.  @file{$(localstatedir)}
+should normally be @file{/usr/local/var}, but write it as
+@file{$(prefix)/var}.
+(If you are using Autoconf, write it as @samp{@@localstatedir@@}.)
+
+@item libdir
+The directory for object files and libraries of object code.  Do not
+install executables here, they probably ought to go in @file{$(libexecdir)}
+instead.  The value of @code{libdir} should normally be
+@file{/usr/local/lib}, but write it as @file{$(exec_prefix)/lib}.
+(If you are using Autoconf, write it as @samp{@@libdir@@}.)
+
+@item infodir
+The directory for installing the Info files for this package.  By
+default, it should be @file{/usr/local/info}, but it should be written
+as @file{$(prefix)/info}.
+(If you are using Autoconf, write it as @samp{@@infodir@@}.)
+
+@item lispdir
+The directory for installing any Emacs Lisp files in this package.  By
+default, it should be @file{/usr/local/share/emacs/site-lisp}, but it
+should be written as @file{$(prefix)/share/emacs/site-lisp}.
+
+If you are using Autoconf, write the default as @samp{@@lispdir@@}.
+In order to make @samp{@@lispdir@@} work, you need the following lines
+in your @file{configure.in} file:
+
+@example
+lispdir='$@{datadir@}/emacs/site-lisp'
+AC_SUBST(lispdir)
+@end example
+
+@item includedir
+@c rewritten to avoid overfull hbox --roland
+The directory for installing header files to be included by user
+programs with the C @samp{#include} preprocessor directive.  This
+should normally be @file{/usr/local/include}, but write it as
+@file{$(prefix)/include}.
+(If you are using Autoconf, write it as @samp{@@includedir@@}.)
+
+Most compilers other than GCC do not look for header files in directory
+@file{/usr/local/include}.  So installing the header files this way is
+only useful with GCC.  Sometimes this is not a problem because some
+libraries are only really intended to work with GCC.  But some libraries
+are intended to work with other compilers.  They should install their
+header files in two places, one specified by @code{includedir} and one
+specified by @code{oldincludedir}.
+
+@item oldincludedir
+The directory for installing @samp{#include} header files for use with
+compilers other than GCC.  This should normally be @file{/usr/include}.
+(If you are using Autoconf, you can write it as @samp{@@oldincludedir@@}.)
+
+The Makefile commands should check whether the value of
+@code{oldincludedir} is empty.  If it is, they should not try to use
+it; they should cancel the second installation of the header files.
+
+A package should not replace an existing header in this directory unless
+the header came from the same package.  Thus, if your Foo package
+provides a header file @file{foo.h}, then it should install the header
+file in the @code{oldincludedir} directory if either (1) there is no
+@file{foo.h} there or (2) the @file{foo.h} that exists came from the Foo
+package.
+
+To tell whether @file{foo.h} came from the Foo package, put a magic
+string in the file---part of a comment---and @code{grep} for that string.
+@end table
+
+Unix-style man pages are installed in one of the following:
+
+@table @samp
+@item mandir
+The top-level directory for installing the man pages (if any) for this
+package.  It will normally be @file{/usr/local/man}, but you should
+write it as @file{$(prefix)/man}.
+(If you are using Autoconf, write it as @samp{@@mandir@@}.)
+
+@item man1dir
+The directory for installing section 1 man pages.  Write it as
+@file{$(mandir)/man1}.
+@item man2dir
+The directory for installing section 2 man pages.  Write it as
+@file{$(mandir)/man2}
+@item @dots{}
+
+@strong{Don't make the primary documentation for any GNU software be a
+man page.  Write a manual in Texinfo instead.  Man pages are just for
+the sake of people running GNU software on Unix, which is a secondary
+application only.}
+
+@item manext
+The file name extension for the installed man page.  This should contain
+a period followed by the appropriate digit; it should normally be @samp{.1}.
+
+@item man1ext
+The file name extension for installed section 1 man pages.
+@item man2ext
+The file name extension for installed section 2 man pages.
+@item @dots{}
+Use these names instead of @samp{manext} if the package needs to install man
+pages in more than one section of the manual.
+@end table
+
+And finally, you should set the following variable:
+
+@table @samp
+@item srcdir
+The directory for the sources being compiled.  The value of this
+variable is normally inserted by the @code{configure} shell script.
+(If you are using Autconf, use @samp{srcdir = @@srcdir@@}.)
+@end table
+
+For example:
+
+@smallexample
+@c I have changed some of the comments here slightly to fix an overfull
+@c hbox, so the make manual can format correctly. --roland
+# Common prefix for installation directories.
+# NOTE: This directory must exist when you start the install.
+prefix = /usr/local
+exec_prefix = $(prefix)
+# Where to put the executable for the command `gcc'.
+bindir = $(exec_prefix)/bin
+# Where to put the directories used by the compiler.
+libexecdir = $(exec_prefix)/libexec
+# Where to put the Info files.
+infodir = $(prefix)/info
+@end smallexample
+
+If your program installs a large number of files into one of the
+standard user-specified directories, it might be useful to group them
+into a subdirectory particular to that program.  If you do this, you
+should write the @code{install} rule to create these subdirectories.
+
+Do not expect the user to include the subdirectory name in the value of
+any of the variables listed above.  The idea of having a uniform set of
+variable names for installation directories is to enable the user to
+specify the exact same values for several different GNU packages.  In
+order for this to be useful, all the packages must be designed so that
+they will work sensibly when the user does so.
+
+@node Standard Targets
+@section Standard Targets for Users
+
+All GNU programs should have the following targets in their Makefiles:
+
+@table @samp
+@item all
+Compile the entire program.  This should be the default target.  This
+target need not rebuild any documentation files; Info files should
+normally be included in the distribution, and DVI files should be made
+only when explicitly asked for.
+
+By default, the Make rules should compile and link with @samp{-g}, so
+that executable programs have debugging symbols.  Users who don't mind
+being helpless can strip the executables later if they wish.
+
+@item install
+Compile the program and copy the executables, libraries, and so on to
+the file names where they should reside for actual use.  If there is a
+simple test to verify that a program is properly installed, this target
+should run that test.
+
+Do not strip executables when installing them.  Devil-may-care users can
+use the @code{install-strip} target to do that.
+
+If possible, write the @code{install} target rule so that it does not
+modify anything in the directory where the program was built, provided
+@samp{make all} has just been done.  This is convenient for building the
+program under one user name and installing it under another.
+
+The commands should create all the directories in which files are to be
+installed, if they don't already exist.  This includes the directories
+specified as the values of the variables @code{prefix} and
+@code{exec_prefix}, as well as all subdirectories that are needed.
+One way to do this is by means of an @code{installdirs} target
+as described below.
+
+Use @samp{-} before any command for installing a man page, so that
+@code{make} will ignore any errors.  This is in case there are systems
+that don't have the Unix man page documentation system installed.
+
+The way to install Info files is to copy them into @file{$(infodir)}
+with @code{$(INSTALL_DATA)} (@pxref{Command Variables}), and then run
+the @code{install-info} program if it is present.  @code{install-info}
+is a program that edits the Info @file{dir} file to add or update the
+menu entry for the given Info file; it is part of the Texinfo package.
+Here is a sample rule to install an Info file:
+
+@comment This example has been carefully formatted for the Make manual.
+@comment Please do not reformat it without talking to roland@gnu.ai.mit.edu.
+@smallexample
+$(DESTDIR)$(infodir)/foo.info: foo.info
+        $(POST_INSTALL)
+# There may be a newer info file in . than in srcdir.
+        -if test -f foo.info; then d=.; \
+         else d=$(srcdir); fi; \
+        $(INSTALL_DATA) $$d/foo.info $(DESTDIR)$@@; \
+# Run install-info only if it exists.
+# Use `if' instead of just prepending `-' to the
+# line so we notice real errors from install-info.
+# We use `$(SHELL) -c' because some shells do not
+# fail gracefully when there is an unknown command.
+        if $(SHELL) -c 'install-info --version' \
+           >/dev/null 2>&1; then \
+          install-info --dir-file=$(DESTDIR)$(infodir)/dir \
+                       $(DESTDIR)$(infodir)/foo.info; \
+        else true; fi
+@end smallexample
+
+When writing the @code{install} target, you must classify all the
+commands into three categories: normal ones, @dfn{pre-installation}
+commands and @dfn{post-installation} commands.  @xref{Install Command
+Categories}.
+
+@item uninstall
+Delete all the installed files---the copies that the @samp{install}
+target creates.
+
+This rule should not modify the directories where compilation is done,
+only the directories where files are installed.
+
+The uninstallation commands are divided into three categories, just like
+the installation commands.  @xref{Install Command Categories}.
+
+@item install-strip
+Like @code{install}, but strip the executable files while installing
+them.  In simple cases, this target can use the @code{install} target in
+a simple way:
+
+@smallexample
+install-strip:
+        $(MAKE) INSTALL_PROGRAM='$(INSTALL_PROGRAM) -s' \
+                install
+@end smallexample
+
+But if the package installs scripts as well as real executables, the
+@code{install-strip} target can't just refer to the @code{install}
+target; it has to strip the executables but not the scripts.
+
+@code{install-strip} should not strip the executables in the build
+directory which are being copied for installation.  It should only strip
+the copies that are installed.
+
+Normally we do not recommend stripping an executable unless you are sure
+the program has no bugs.  However, it can be reasonable to install a
+stripped executable for actual execution while saving the unstripped
+executable elsewhere in case there is a bug.
+
+@comment The gratuitous blank line here is to make the table look better
+@comment in the printed Make manual.  Please leave it in.
+@item clean
+
+Delete all files from the current directory that are normally created by
+building the program.  Don't delete the files that record the
+configuration.  Also preserve files that could be made by building, but
+normally aren't because the distribution comes with them.
+
+Delete @file{.dvi} files here if they are not part of the distribution.
+
+@item distclean
+Delete all files from the current directory that are created by
+configuring or building the program.  If you have unpacked the source
+and built the program without creating any other files, @samp{make
+distclean} should leave only the files that were in the distribution.
+
+@item mostlyclean
+Like @samp{clean}, but may refrain from deleting a few files that people
+normally don't want to recompile.  For example, the @samp{mostlyclean}
+target for GCC does not delete @file{libgcc.a}, because recompiling it
+is rarely necessary and takes a lot of time.
+
+@item maintainer-clean
+Delete almost everything from the current directory that can be
+reconstructed with this Makefile.  This typically includes everything
+deleted by @code{distclean}, plus more: C source files produced by
+Bison, tags tables, Info files, and so on.
+
+The reason we say ``almost everything'' is that running the command
+@samp{make maintainer-clean} should not delete @file{configure} even if
+@file{configure} can be remade using a rule in the Makefile.  More generally,
+@samp{make maintainer-clean} should not delete anything that needs to
+exist in order to run @file{configure} and then begin to build the
+program.  This is the only exception; @code{maintainer-clean} should
+delete everything else that can be rebuilt.
+
+The @samp{maintainer-clean} target is intended to be used by a maintainer of
+the package, not by ordinary users.  You may need special tools to
+reconstruct some of the files that @samp{make maintainer-clean} deletes.
+Since these files are normally included in the distribution, we don't
+take care to make them easy to reconstruct.  If you find you need to
+unpack the full distribution again, don't blame us.
+
+To help make users aware of this, the commands for the special
+@code{maintainer-clean} target should start with these two:
+
+@smallexample
+@@echo 'This command is intended for maintainers to use; it'
+@@echo 'deletes files that may need special tools to rebuild.'
+@end smallexample
+
+@item TAGS
+Update a tags table for this program.
+@c ADR: how?
+
+@item info
+Generate any Info files needed.  The best way to write the rules is as
+follows:
+
+@smallexample
+info: foo.info
+
+foo.info: foo.texi chap1.texi chap2.texi
+        $(MAKEINFO) $(srcdir)/foo.texi
+@end smallexample
+
+@noindent
+You must define the variable @code{MAKEINFO} in the Makefile.  It should
+run the @code{makeinfo} program, which is part of the Texinfo
+distribution.
+
+Normally a GNU distribution comes with Info files, and that means the
+Info files are present in the source directory.  Therefore, the Make
+rule for an info file should update it in the source directory.  When
+users build the package, ordinarily Make will not update the Info files
+because they will already be up to date.
+
+@item dvi
+Generate DVI files for all Texinfo documentation.
+For example:
+
+@smallexample
+dvi: foo.dvi
+
+foo.dvi: foo.texi chap1.texi chap2.texi
+        $(TEXI2DVI) $(srcdir)/foo.texi
+@end smallexample
+
+@noindent
+You must define the variable @code{TEXI2DVI} in the Makefile.  It should
+run the program @code{texi2dvi}, which is part of the Texinfo
+distribution.@footnote{@code{texi2dvi} uses @TeX{} to do the real work
+of formatting. @TeX{} is not distributed with Texinfo.}  Alternatively,
+write just the dependencies, and allow GNU @code{make} to provide the command.
+
+@item dist
+Create a distribution tar file for this program.  The tar file should be
+set up so that the file names in the tar file start with a subdirectory
+name which is the name of the package it is a distribution for.  This
+name can include the version number.
+
+For example, the distribution tar file of GCC version 1.40 unpacks into
+a subdirectory named @file{gcc-1.40}.
+
+The easiest way to do this is to create a subdirectory appropriately
+named, use @code{ln} or @code{cp} to install the proper files in it, and
+then @code{tar} that subdirectory.
+
+Compress the tar file with @code{gzip}.  For example, the actual
+distribution file for GCC version 1.40 is called @file{gcc-1.40.tar.gz}.
+
+The @code{dist} target should explicitly depend on all non-source files
+that are in the distribution, to make sure they are up to date in the
+distribution.
+@ifset CODESTD
+@xref{Releases, , Making Releases}.
+@end ifset
+@ifclear CODESTD
+@xref{Releases, , Making Releases, standards, GNU Coding Standards}.
+@end ifclear
+
+@item check
+Perform self-tests (if any).  The user must build the program before
+running the tests, but need not install the program; you should write
+the self-tests so that they work when the program is built but not
+installed.
+@end table
+
+The following targets are suggested as conventional names, for programs
+in which they are useful.
+
+@table @code
+@item installcheck
+Perform installation tests (if any).  The user must build and install
+the program before running the tests.  You should not assume that
+@file{$(bindir)} is in the search path.
+
+@item installdirs
+It's useful to add a target named @samp{installdirs} to create the
+directories where files are installed, and their parent directories.
+There is a script called @file{mkinstalldirs} which is convenient for
+this; you can find it in the Texinfo package.
+@c It's in /gd/gnu/lib/mkinstalldirs.
+You can use a rule like this:
+
+@comment This has been carefully formatted to look decent in the Make manual.
+@comment Please be sure not to make it extend any further to the right.--roland
+@smallexample
+# Make sure all installation directories (e.g. $(bindir))
+# actually exist by making them if necessary.
+installdirs: mkinstalldirs
+        $(srcdir)/mkinstalldirs $(bindir) $(datadir) \
+                                $(libdir) $(infodir) \
+                                $(mandir)
+@end smallexample
+
+This rule should not modify the directories where compilation is done.
+It should do nothing but create installation directories.
+@end table
+
+@node Install Command Categories
+@section Install Command Categories
+
+@cindex pre-installation commands
+@cindex post-installation commands
+When writing the @code{install} target, you must classify all the
+commands into three categories: normal ones, @dfn{pre-installation}
+commands and @dfn{post-installation} commands.
+
+Normal commands move files into their proper places, and set their
+modes.  They may not alter any files except the ones that come entirely
+from the package they belong to.
+
+Pre-installation and post-installation commands may alter other files;
+in particular, they can edit global configuration files or data bases.
+
+Pre-installation commands are typically executed before the normal
+commands, and post-installation commands are typically run after the
+normal commands.
+
+The most common use for a post-installation command is to run
+@code{install-info}.  This cannot be done with a normal command, since
+it alters a file (the Info directory) which does not come entirely and
+solely from the package being installed.  It is a post-installation
+command because it needs to be done after the normal command which
+installs the package's Info files.
+
+Most programs don't need any pre-installation commands, but we have the
+feature just in case it is needed.
+
+To classify the commands in the @code{install} rule into these three
+categories, insert @dfn{category lines} among them.  A category line
+specifies the category for the commands that follow.
+
+A category line consists of a tab and a reference to a special Make
+variable, plus an optional comment at the end.  There are three
+variables you can use, one for each category; the variable name
+specifies the category.  Category lines are no-ops in ordinary execution
+because these three Make variables are normally undefined (and you
+@emph{should not} define them in the makefile).
+
+Here are the three possible category lines, each with a comment that
+explains what it means:
+
+@smallexample
+        $(PRE_INSTALL)     # @r{Pre-install commands follow.}
+        $(POST_INSTALL)    # @r{Post-install commands follow.}
+        $(NORMAL_INSTALL)  # @r{Normal commands follow.}
+@end smallexample
+
+If you don't use a category line at the beginning of the @code{install}
+rule, all the commands are classified as normal until the first category
+line.  If you don't use any category lines, all the commands are
+classified as normal.
+
+These are the category lines for @code{uninstall}:
+
+@smallexample
+        $(PRE_UNINSTALL)     # @r{Pre-uninstall commands follow.}
+        $(POST_UNINSTALL)    # @r{Post-uninstall commands follow.}
+        $(NORMAL_UNINSTALL)  # @r{Normal commands follow.}
+@end smallexample
+
+Typically, a pre-uninstall command would be used for deleting entries
+from the Info directory.
+
+If the @code{install} or @code{uninstall} target has any dependencies
+which act as subroutines of installation, then you should start
+@emph{each} dependency's commands with a category line, and start the
+main target's commands with a category line also.  This way, you can
+ensure that each command is placed in the right category regardless of
+which of the dependencies actually run.
+
+Pre-installation and post-installation commands should not run any
+programs except for these:
+
+@example
+[ basename bash cat chgrp chmod chown cmp cp dd diff echo
+egrep expand expr false fgrep find getopt grep gunzip gzip
+hostname install install-info kill ldconfig ln ls md5sum
+mkdir mkfifo mknod mv printenv pwd rm rmdir sed sort tee
+test touch true uname xargs yes
+@end example
+
+@cindex binary packages
+The reason for distinguishing the commands in this way is for the sake
+of making binary packages.  Typically a binary package contains all the
+executables and other files that need to be installed, and has its own
+method of installing them---so it does not need to run the normal
+installation commands.  But installing the binary package does need to
+execute the pre-installation and post-installation commands.
+
+Programs to build binary packages work by extracting the
+pre-installation and post-installation commands.  Here is one way of
+extracting the pre-installation commands:
+
+@smallexample
+make -n install -o all \
+      PRE_INSTALL=pre-install \
+      POST_INSTALL=post-install \
+      NORMAL_INSTALL=normal-install \
+  | gawk -f pre-install.awk
+@end smallexample
+
+@noindent
+where the file @file{pre-install.awk} could contain this:
