"""This script finds all '.properties-MERGED' files and writes relative path, key, and value to a CSV file.
This script requires the python libraries: gitpython, jproperties, pyexcel-xlsx, xlsxwriter and pyexcel.  As a
consequence, it also requires git >= 1.7.0 and python >= 3.4.  This script relies on fetching 'HEAD' from current
branch.  So make sure repo is on correct branch (i.e. develop).
