@smithfox: Thx for your translation. I have commited it now - see revision 3313.. Because of some last minute changes there are 2 untranslated and 2 fuzzy strings - see http://pivotx.net/dev/translation-stats.html.
@Winjer: A leaf directory is a directory with no sub directories - just like leaves on a tree. "nicename" means a nice name (generated from the file name), but you might as well leave it untranslated. The "robot" refers to search engine crawlers. (The explanation for "Filter as any robot" option is "Test each sitemap entry against all Disallow rules in robots.txt. User-agent qualifiers are ignored, every Disallow will contribute to URI exclusion.") Hope this helps.
