SHORT_DESC = Bash is short for born again shell.

define LONG_DESC
	Bash is the shell, or command language interpreter, that will appear in \
	the GNU operating system. Bash is an sh-compatible shell that incorporates \
	useful features from the Korn shell (ksh) and C shell (csh). It is intended \
	to conform to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard.
