Re: [docbook-apps] gentext.template eats 1/3 of CPU

I imagine these belong to your client, but would it  be possible make 
something like this freely available?  I know:  just what does the user 
want and not want.  Not easy.  And anyway, not DocBook philosophy.  Just 
a thought, there's a lot of Docbook I never use, but I'll stick with the 
full DocBook.
