# QM file converter for FreeCAD translators
#
# This script was written for the international community engaged in the work of translating and improving
# FreeCAD GUI translations. In the first version, this work was done by a long command with pipelined processing.
# However when more people of different nationalities started to use this solution modifying the command could be
# cumbersome. Therefore, this all-purpose versatile bash script was created to solve several inconveniences, at
# the same time as it recognizes the language of the source files.
