Hi Dimitry,

Yes my Perl version does all that in 1 pass, but one of the things I want to do is have it generate for different targets.  Groff was my initial one.  I wan't creating any kind of AST but I think I'll want to do that in my rewrite to make things simpler and allow for generating for other targets like maybe Latex, or epub etc...

I'll have a look, thanks for the link!
