 // Tool to upload an exe/dll and its associated symbols to an HTTP server.
 // The PDB file is located automatically, using the path embedded in the
 // executable.  The upload is sent as a multipart/form-data POST request,
 // with the following parameters:
 //  code_file: the basename of the module, e.g. "app.exe"
 //  debug_file: the basename of the debugging file, e.g. "app.pdb"
 //  debug_identifier: the debug file's identifier, usually consisting of
 //                    the guid and age embedded in the pdb, e.g.
 //                    "11111111BBBB3333DDDD555555555555F"
 //  version: the file version of the module, e.g. "1.2.3.4"
 //  os: the operating system that the module was built for, always
 //      "windows" in this implementation.
 //  cpu: the CPU that the module was built for, typically "x86".
 //  symbol_file: the contents of the breakpad-format symbol file
