 """Usage: <win-path-to-pdb.pdb>
 This tool will take a PDB on the command line, extract the source files that
 were used in building the PDB, query SVN for which repository and revision
 these files are at, and then finally write this information back into the PDB
 in a format that the debugging tools understand.  This allows for automatic
 source debugging, as all of the information is contained in the PDB, and the
 debugger can go out and fetch the source files via SVN.
