Script to rebuild server zip from modified Launcher configuration/modpack?

[Andrew Bradley]

There doesn't seem to be a subforum for this kind of question, so I apologize if it's in the wrong section.

I have modified the Technic Launcher to download from my own mirror of Technic instead of mirror.technicpack.net. This allows to me to change the modpack configuration to add and remove mods. When I make changes to the client-side mod configuration, my friends' clients auto-update. But that's only the client. Which brings me to my question:

Is there an automated way to create the Tekkit_Server.zip/Technic_Server.zip/Voltz_Server.zip based on the launcher's configuration (modpack.yml)?

(I'm referring to the server downloads from TechnicPack.net)

I notice that IceWolf pushes the new server zip packages to Github so I'm assuming he's the guy that creates them. Does he use some sort of script to automate the process, or does he do it all manually? Does he use the launcher to generate the zip? The contents of a server zip are very close to, for example, ".techniclauncher/tekkit", which is why I ask.
