# the help subsystem
#
# It is a very simple system in that you type in 'help <cmd>' and it
-# looks for a file called <cmd>.hlp in either the local_cmd directory
+# looks for a file called command.hlp in either the local_cmd directory
# or the cmd directory (in that order).
#
-# if you just type in 'help' by itself you get what is in 'help.hlp'.
