-SUMMARY="Get information about a class and its structure"
-DESCRIPTION="Class::Inspector allows you to get information about a loaded class. Most or all of \
-this information can be found in other ways, but they aren't always very friendly, and usually \
-involve a relatively high level of Perl wizardry, or strange and unusual looking code. \
-Class::Inspector attempts to provide an easier, more friendly interface to this information."
+SUMMARY="Patches text with given patch"
+DESCRIPTION="Text::Patch combines source text with given diff (difference) data. Diff data is \
+produced by Text::Diff module or by the standard diff utility (man diff, see -u option)."
