I found the way svk dispatched to it's various sub-commands interesting,
although the details have faded from my mind.
Scanning through again, I think svk calls
SVK::Command->invoke(..., $cmd, ... @ARGV);
(SVK::Command->invoke loads the corresponding class SVK::Command::$name)
SVK::Command is a base class and namespace for other commands, providing
some option handling and utility methods. Commands are in their own
modules like SVK::Command::Add. They provide a "run" method,
options list and various other things. This might be a bit
overblown for your situation.
PS. "XD" is Working Copy. This may help make the code clearer.
In the judgement of the elders, a samurai's obstinacy should be excessive.
A thing done with moderation may later be judged insufficient. I have heard
that when one thinks he has gone too far, he will not have erred. This sort
of rule should not be forgotten. -- Hagakure http://bereft.net/hagakure/
