Tk::Submethods(3) add aliases for tk sub-commands


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


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.
