This project has been abandoned. Spaar has continued my work over at the Besiege forum: http://forum.spiderlinggames.co.uk/index.php?threads/spaars-mod-loader-1-7-1-besiege-v0-45a.519/
This is a prototype for a modloader for Besiege. It is unfinished, buggy, and messy.
Feel free to use my code as a reference for your own projects, but I would advise against using the code as is :)
