The idea is to create builds out of a .c3p file via a command line.
In our workflow we are creating Playable Ads for various platforms (MRAID, Facebook, DAPI, etc.) and some of those are later localized.
Right now we need to keep separate projects for each combination of platform and language. This obviously can get out of hand quickly, to say the least.
With the possibility of building via a command line we could develop a toolchain to modify the base project to fit the specifications of each platform, creating new projects and then build those.
That way we just need to mantain the base project, any bug we solve, any modification we need to make, etc, could then be propagated to all the other versions.
