+      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.  It offers
+      functional improvements over sh for both programming and
+      interactive use.  In addition, most sh scripts can be run by
+      Bash without modification.
