A very basic wrapper to the libmpq library. It allows you to read, decrypt and unpack MPQ files.
require 'mpq'
archive = MPQ("test/fixtures/replay.SC2replay")
# => #<MPQ::Archive:0x1003732b8 @path="test/fixtures/replay.SC2replay">
# list the files in the archive
archive.manifest
# => ["replay.attributes.events", "replay.details", ... truncated for legibility
archive.read_file('replay.message.events')
# => "\000\"\200\000\000\034\000\000 ... truncated for legibility
