It's particularly useless for anything else, really. Not to mention it's in a completely un-portable format. One can only hope this was generated automatically.
"Un-portable" in that it wraps the win32 API rather than implementing the API. But it's actually a pretty handy format if you wanted to generate wrappers for other languages -- replace a couple base types/functions and have it emit code to wrap the Win32 API for any other language.
And yeah, it's pretty obviously automatically generated.
