Hi,
I said in february that we got a new friendly extractor, which autodiscovers the Drupal files, so we don't need any command line magic. Today's update means that we don't need any command line at all. Just drop the extractor in any folder under Drupal in your webroot, access the file via the webserver in a browser, and see the pot files generating. The script still autodiscovers all Drupal related files in all subfolders recursively.
Grab the new file from CVS or: http://href.hu/x/1i74 (a shortened CVS checkout address).
Ps. actually the extractor worked over the web fine already, it just printed an ugly line and then nothing. This was changed today. It still prints all the t() errors found, so those can be fixed.
