Subject: LP#1750912 - Add add_translations.py convenience script to i18n tools.
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=f09ae174cff3b3392e9399f1fff2f8d2e8b8b94d;p=evergreen%2Fmasslnc.git

LP#1750912 - Add add_translations.py convenience script to i18n tools.

This script was authored by Jason Stephenson, who has kindly
agreed to add it to the Evergreen source tree.  As Jason suggested,
I modified the GPL version number to 2 to be in line with the
Evergreen project's licensing requirements.
