Usage: complete [<cword> <word>...]
-In the first form, the command prints all possible completions to stdout.
-This can be used from the completion function of the shell.
+When executed without argument the command writes bash code to
+stdout. This code is suitable to be evaled from .bashrc to enable
+completion.
-Completion code suitable to be evaled is written to stdout if no argument
-was given.
+If at least one argument is given, all possible completions are
+written to stdout. This can be used from the completion function of
+the subcommand.

# Aborts on programming errors such as missing or invalid option string. On
# success $result contains shell code that can be eval'ed. For each defined
# option x, the local variable o_x will be created when calling eval "$result".
-# o_x contains true/false for options without an argument or the emtpy string/the
-# given argument, depending on whether this option was contained in the "$@"
-# array.
+# o_x contains true/false for options without argument and either the emtpy
+# string or the given argument for options that take an argument.
#
# Example:
# gsu_getopts abc:x:y
# eval "$result"
-# [[ $ret -lt 0 ]] && return
+# (($ret < 0)) && return

-# [[ "$o_a" = "true ]] && echo "The -a flag was given"
