# NAME

Tk::Submethods - add aliases for tk sub-commands

# SYNOPSIS

      use Tk::Submethods ( 'command1' => [qw(sub1 sub2 sub3)],
                           'command2' => [qw(sub1 sub2 sub3)]);

# DESCRIPTION

Creates `->commandSub(...)` as an alias for `->command('sub',...)` e.g. `->grabRelease` for `->grab('release')`.

For each command/subcommand pair this creates a closure with command and subcommand as bound lexical variables and assigns a reference to this to a 'glob' in the callers package.

Someday the sub-commands may be created directly in the C code.
