Petroglyph Meg file library

MEGA files are a format used by Petroglyph for various games including Star Wars: Empire at War, Universe at War: Earth Assault, Guardians of Graxia, Rise of Immortals, Grey Goo, and Great War: Western Front.

This repo provides a Rust Library and other tools for working with them.

The parsing and encoding is based on the format descriptions provided here by some of the Modders who first enabled Empire at War modding.

Why?

Q: You're like 20 years late to this party. Why make this now?

Mostly for fun. Also because the MEGA file editor produced by Mike Lankamp is a C# GUI intended for Windows and I'm a Linux dev who likes CLI tools.

There are some tweaks I like to apply to all projectiles in Empire at War (e.g. making all lasers faster), and I tend to write scripts to do that rather than hand editing the XML config files. By making this a library, I can write a script that directly extracts and edits files from the game's MEGA files without needing to provide it a pre-extracted bundle of XML "source" files to work with.
