+# Currently github can create automatically the source pack, but it fails to include 
+# all the files belonging to submodules, hence making this function unsuitable for this project:

+# This script allows to download either a specific branch or a tagged version of Polycube, 
+# and create both a ZIP and a TAR containing all the sources.
