Erlang documentation sources

[Tamas Patrovics]

Hi,

I'm looking for the documentation sources from which the erlang
documentation (man, html) is generated? Are they available somewhere?

They don't seem to be generated from the code, so I suppose there is a
documentation source (iSGML? XML?)  which is used to generate
documentation in various format..

I went to the Erlang download page, but I could only find the html and
man versions there.

Thanks in advance,
