One good idea would be to have a scrip that comes with any version of forge src (extracts to the mcp directory once install is done) that can grab pre-decompiled src files from newer versions of forge and copy them to our src directory.

This would be useful as, although I only work with recommended builds which are every few weeks and then stop for months or until the next minecraft update), you won't have to keep redownloading forge src and waiting ages for it to re-decompile.

This would be useful and easily done for within minecraft versions (different versions of forge for the same minecraft version).

However I do understand newer versions of minecraft compile differently so need new workspaces. That is fine, it's just the fact that new builds for the same mc version can only be acquired through another decompile.

We're actually moving away from decompiling minecraft being the standard. 1.7 development will be gradle based and decompiled only if demanded.

Your source will be separated from Minecraft's source.
