Packaging

A .deb is a control file plus a tree that is copied onto the filesystem. Everything installs under /Library/TweakInject.

The control file

Dependencies worth declaring

com.doraorak.preferenceloaderx if your tweak ships a preference bundle and you want its settings to appear in System Settings.
mobilesubstrate if you hook functions, which is what provides MSHookFunction.

Version drift

The version inside the .deb and the version in the store listing have to agree. When they do not, the installed record reports the payload's version while the listing advertises another, and the app offers an update for something just installed.
