NEED TO UPDATE THIS FILE FOR OSIRIS!!!

There are three kinds of help provided:

    help "command"   will provide help on each command.

    help "category"  will provide help on one of the following categories:

                     ao      adaptive optics commands
                     det     detector commands
                     disp    display commands
                     info    informational commands
                     mot     motor commands
                     tel     telescope commands

    The third type of help comes into play if the argument you have provided 
    is neither an OSIRIS command or one of the categories above.  In this
    situation the command tries to determine whether the argument is an
    alias or some other command in the user's PATH.  If the latter, it
    will attempt to print out the man page entry for that command.
