# Commands:
# compl.add [-null] [-nomatch] <command pattern> <command parser name>
# or
# compl.add <[-nulll] [-nomatch]> <command parser name>
# to add patterns and assciated parsers or just parsers to null and nomatch
# condition. (See notes below for me info)
#
# compl.list Just list everything out..
# don't clobber existing lists when reloading complete

# alias compl.add
# Usage: compl.add [-null] [-nomatch] <command pattern> <command parser>
# Usage: compl.add <[-null] [-nomatch]> <command parser>
# e.g. compl.add /msg message_parser will call the message_parser
# when TAB is pressed and /msg
# is the current command on the
# input line
# -null specifies that the given <command parser> should be used when
# TAB is pressed and the input line is blank
# -nomatch specifies that the given <command parser> should be used
# when the current command at the head of the input line is not
# found in the list of <command pattern>s
# can use just compl.add -null message_parser
# or compl.add -null -nomatch message_parser
