For those interested in the handbook project that is just now getting off the ground, I highly encourage you to check out this latest post by Jane Wells on the WP Docs mailing list. A post about this will be published on the WordPress Dev blog in the near future.

That was a good read. It will be interesting to see the end result.
Hopefully they will include some sort of theming capability to the handbooks since reading the inspiration source (http://svnbook.red-bean.com) is difficult I think. Hard to overview also.
@Andreas Nurbo – Hmm, I wonder how difficult it will be for them to theme the handbooks and if that theme will transfer into the PDF file for the handbook. I’m pretty sure most of the handbook or all of it will be in HTML so themeing shouldn’t be hard with CSS.
