I present you Arma Mission Compressor mk 1, a powerfull tool removing all comments and newlines (save the #includes), as well as all .txt and .gitignore files from your mission folder.
To use it just drag&drop your mission folder on the executable and voila! It removes 290kB (sic!) from barebone F2 itself!

It requires .net framework 3.5, but I believe you have it installed already.
If you decide to use it and have any problems or suggestions, let me know!
EDIT 2014-02-10:
I received comments from total of 1 happy users and decided to upload new version. This time it removes /* */ comment blocks, and (hopefully) recognizes quoted strings.
