Progress is good. The parser doesn’t yet understand type 0x2A yet, but it will soon…

The parser library is a plain-vanilla C++ library, cross platform and embeddable in just about anything. I’m mainly focused on building an AST of the cache file format at this point. We can walk the AST and fetch the needed data later, which is the “easy part.” This is not a “find-magic-byte sequence and use fixed offsets” type parser

You can track progress at gitorious.org/libevecache.
