mass update of po files in Rosetta

[Valient Gough]

I recently released a new version of my software, so I downloaded the PO 
files from Rosetta (using a perl script which I posted once before) and 
merged them with my local copies and fixed up the usual formatting 
errors, etc.

What is the procedure for updating Rosetta with the current versions 
from my software?  Have you guys created a way to bulk upload all the 
.po files, or do I need to upload one at a time (or script it on the 
client side)?

Since I'll be updating both the main template and each language's .po 
file, is there a certain order I should upload them in? 

Also, in the past when I've uploaded .po files, the "Last Contributor" 
changes to my name.  I've even tried setting the Last-Translator field 
in the .po file to correspond to the current last contributor, but it 
seems it still gets set to my name after uploading the .po.  Any 
suggestions?

regards,
