Instead of including every theme in the tarball, I've decided to just provide an area where you can download whatever you want...
If you have a bashblogger theme you'd like to share, read the Theme Submission Guidelines.
It's important to follow, at least the packaging conventions, if not the naming conventions as the stylesheet is now considered a part of a theme. If yo u hand-edit the stylesheet in the root directory and the use the theme editor from within bashblogger, it will overwrite your hand edits.
I'm just saying...
Also, with the 0.3.5.x series, partial templates are exposed to the user in ~/.bashblogger/templates. If you're interested in adding foaf, xfn, or any of the other th ings where you'll need to expose and modify the header, you can make edits to the Header_Footer file.
All of the templates are commented fairly well (to me) and should provide enough hooks for users to add whatever they need to their site. Of course, I'm open to suggestions.
