Preseeding ubiquity, how?

[Fabrizio Balliano]

Hi to all,
as a developer of a few Ubuntu derivatives I followed the last threads
about the barebone X session for ubiquity, the "only-ubiquity" boot
option it's really cool for me so I can avoid remastering alternate cd
that's a bit difficult.

Now the question, googleing around it seems possible to preeseed
ubiquity but I can't find a guide or some kind of documentation, I'm
looking at the source code but... if someone knows where to find a bit
of doc it would be wonderful.

thank you all
bye!
