It has happened quite a few times to me that after committing new po files, the next morning only to find it fails drupal.org packaging script. The error could simply be a typo in header, or mismatching line breaks. PoEdit doesn't seem to be able to catch the latter. The fact I had to file a support request to have  release node removed before I could cvs untag it, makes it more frustrating.

So I am wondering if the drupal.org packaging script available for download, or is there a similar checker script I can run before committing to CVS?
