+# This script can be used to add or remove a sentence from all the language
+# files. It's really simple and hacking: just edit this files adding lines
+# In the corresponsing fields (add, remove) and run it.
+#
+# Quick note: run it from the "root" directory of the project: it searches for
+# ./lang/ so the correct command should be `python3 scripts/process_lang.py`.
