# generate-po-from-template.sh:
|

# update an existing <lang>.po file from the POT (gettext template for
|

# translations)
|
||||
#
|
||||
# The goal is to take the opportunity to do a little bit more than what
|
||||
# msgmerge does, including:
|
||||
# - copying the full template if the language file does not yet exist;
|
||||
# - post-process a few fields that it does not change but we may wish to
|
||||
# see updated (project name, version, ...)
