I am attempting to learn how create mods, and documentation with the forge tool is not detailed enough for advanced topics.  Mods I have downloaded do not include source text files, so it is hard to figure out what was changed.  Can people start providing source text files of the binary entity files, and maybe also a text file for the changes to the gameplay.constants file???  I downloaded and used the unit cap mod, and I like it.  All files were binary, and the gameplay.constants file was a full file.  Windows doesn't appear to have a diff command like Unix, and I downloaded a binary editor to see data that didn't make sense.

Any help like this would be appreciated.
