# 0. Compile program with coverage support.
# 1. Clear coverage data. (Recursively delete *.gcda in build dir)
# 2. Run the unit tests.
# 3. Run this script specifying which source files the coverage should be performed on.
#
# This script will then use gcov to generate .gcov files in the directory specified
# via the COV_PATH var. This should probably be the same as your cmake build dir.
#
# It then parses the .gcov files to convert them into the Coveralls JSON format:
