What is Fwatch?

Fwatch is a program extending Operation Flashpoint's scripting functionality.

It creates a hook on file operations. When the game attempts to open file with a special name then Fwatch takes over. It's able to perform a variety of operations (like read/write text files, manipulate strings, utilize WINAPI) and send results back to the game.

It was created by Kegetys in 2005. This project (which started in the late 2010) is a continuation. It features 97 new commands (123 in total), compatibility with 1.99 and has several old issues fixed.
