I've searched the site and also used Google, but I can't seem to find where the information is.  Sorry for what has to be a dumb question!  Is it possible to run PWG from the command line?  Specifically, I'd like to synchronize dirs and files (after uploading new pics & thumbs) as part of a shell script.  If it's possible, what would the command be?

I've been using PWG for a couple of months now, and love it!  Have a look at the results http://molvray.com/photos if you'd like.  :D
