5 # The purpose of this script is to generate a multi-lingual en po file for
6 # Mailman Core. Multi-lingual PO files use both a .pot file and a reference po
7 # file. The reference in our case is en and is what is displayed in Weblate
8 # when translating.
10 # Since there are no utilities to create multi-lingual reference PO file, this
11 # script exists to solve that purpose. Here is how it works:
13 # It will read the default en po file and set all msgstr to be same as
14 # msgid. The only exception to this is email templates, where the msgid is the
15 # filename of the template and msgstr is the content of that file.
