# Last modified 2024-03-25
#
# Updates description localization template (".pot")
# to capture any new strings, or changes to the main English
# translations, found within the brush description files
# ("filename.txt"), which contain both the textual description
# of the brush in English, plus all languages it has been translated to.
# (As generated by "po2txt.py").
