This branch is a very minimal testing framework to make it easier for future people to reproduce test cases for Windows argument parsing. There are three programs here.

Firstly a C++ program, args.cpp, that output its raw commandline, argc and then each argument in argv:

cl src\args.cpp /nologo /MT /O2 /link /MANIFEST:EMBED /MANIFESTINPUT:src\manifest.xml

gen_test_Cases.rs repeatedly calls args.exe with different command line arguments and saves the output to a file.

gen_test_cases.rs transforms the ouput of the test cases into a form that can be used in library\std\src\sys\windows\args\tests.rs. This only needs to be used when updating standard library tests.
