// 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".
