+SUMMARY="screen - a full-screen terminal window manager" 
+DESCRIPTION="
+Screen is a full-screen window manager that multiplexes a physical \
+terminal between several processes, typically interactive shells. \
+\
+Each virtual terminal provides the functions of the DEC VT100 terminal \
+and, in addition, several control functions from the ANSI X3.64 \
+(ISO 6429) and ISO 2022 standards (e.g., insert/delete line and support \
+for multiple character sets). \
+There is a scrollback history buffer for each virtual terminal and \
+a copy-and-paste mechanism that allows the user to move text regions \
+between windows. When screen is called, it creates a single window \
+with a shell in it (or the specified command) and then gets out of \
+your way so that you can use the program as you normally would. \
+Then, at any time, you can create new (full-screen) windows with \
+other programs in them (including more shells), \
+kill the current window, view a list of the active windows, \
+turn output logging on and off, copy text between windows, \
+view the scrollback history, switch between windows, etc. \
+All windows run their programs completely independent of each other. \
+Programs continue to run when their window is currently not visible \
+and even when the whole screen session is detached from the users terminal. \
+A command-line compatible rm which destroys file contents before unlinking. \
