#!/usr/bin/env python
# This script collects coverage for all unit tests in a specified directory.
# For each test file outputs a binary coverage file produces by the VS tool chain.
# The coverage file can be opened in VS for detailed analysis or be used for reporting.
# For collection of full coverage the binaries should be compiled with /PROFILE linker flag.
