[lxml-dev] documentation split

[Stefan Behnel]

Hi all,

Martijn's recent call got me started on a major restructuring of lxml's
documentation. I mainly split up the humongous api.txt for now and did a bit
of rewriting in main.txt. The split might have left some paragraphs without
context, so I wouldn't mind having somebody take a look over them.

The current version is available from
http://codespeak.net/lxml/dev/

Any help, comments and (preferably) patches against doc/*.txt are very welcome!

Stefan
