Re: [docbook-apps] producing epub 2 (NOT epub 3s) -- how to do it?

The docbook epub directory includes a Ruby script that can 
build an epub2 book.  Have you tried epub/bin/db2epub?

I assumed that the /epub directory is still supported (although the ruby 
script might not work). 

If it is the case that /epub/docbook.xsl 
is no longer supported, then there would probably be a need to have a epub2 
backward compatibility option for the epub3/ stylesheet. 

The 
Smashword error messages indicate that they are unable to read epub2 features:

We have run EPUBcheck on your file, and unfortunately, it has not passed 
validation. The errors found were:

  point; ignored

Smashwords is quickly becoming a major distributor of ebooks -- although 
they've been using an older verison of epubcheck. They accept only epub files 
which can pass the older test. 

Robert, 

If I remember correctly there is an epub  
directory in the stylesheet distribution that creates epub2. It is unsupported 
as Keith is no longer maintaining it.  It may still be a good starting 
point.
