Microsoft has made an effort to open up and document it's proprietary PDB debugging file format, a.k.a program database (.pdb) file, primarily used by Visual Studio Debugger and WinDbg. Apparently, the aim is to open it for use in other compilers/debuggers.

Source code of binary level formats and simple tools that can use PDB format:

There is also a read-only API for accessing PDB format called Debug Interface Access SDK:
