Subject: tools/git-tp-sync: Compare Revisions
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=100c0c1eee3043edf542d1aafd3b0259f510d70f;p=thirdparty%2Futil-linux.git

tools/git-tp-sync: Compare Revisions

The previous version required updating languages through the command
line, or it would download all PO files.

This commit improves the script by comparing the PO-Revision-Date in
the old and new versions, and only commits updated PO files.
