Perfmon .blg file specification / parsing library

Question

Where can I find a detailed, low-level spec for the Perfmon binary .blg file format? Or even better, has anyone written a low level, open source library (preferably in C, but any language would do) for parsing .blg files?

Answer 1

There's a tool called relog that can convert these files to csv or other formats.
