Package ''cmdline'' is a part of [Tcllib].
Documentation can be read online at http://tcllib.sourceforge.net/doc/cmdline.html , and
examples of cmdline usage appear in [ftpd], [htmlparse], and [pop3].

[Glenn Jackman] offers

and
http://groups.google.com/groups?th=84e714d1329a035#link5
as "examples of cmdline in action".





The cmdline package can be used for both programs which accept arguments
via the argv list as well as procs which have specific needs for argument
processing.

----
Here is an example of its use (http://groups.google.com/groups?th=89144039acd5554b):

    package require cmdline

    proc test {args} {
        set options {
            {first.arg  1 "1st arg"}
            {second.arg 2 "2nd arg"}
            {third.arg  3 "3rd arg"}
            {fourth.arg 4 "4th arg"}
        }
         
        # cmdline::getoptions will throw an error for unknown option
        array set params [::cmdline::getoptions args $options]

        # do other stuff...
        parray params
    }                
     
    test -fourth last -first one
