SYNOPSIS

# in script "frobnicate"
multi sub MAIN("foozle")  { say "foozle"  }
multi sub MAIN("barabas") { say "barabas" }
multi sub MAIN("bazzie")  { say "bazzie"  }
use shorten::sub::commands &MAIN;

    $ raku frobnicate foo
    foozle
    $ raku frobnicate ba
    'ba' is ambiguous, matches: barabas bazzie
    $ raku frobnicate bar
    barabas

DESCRIPTION

shorten::sub::commands is a helper module intended to be used for command-line application that have a sub-command structure (in which the first positional parameter indicates what needs to be done, and there is a separate candidate to handle execution of that command).

When used after all MAIN candidates have been defined, it will add another candidate that will allow to shorten the command names to be as short as possible (e.g. just "foo" in the example above, or even just "f" as there is only one candidate that starts with "f".
