[horde] Begin an app with horde: Basic auth needed!

[freeze at free.fr]

Hi,
   I'd like to create my website based on horde, so they can read their emails 
directly: They'll login only once. I've installer imp/horde & turba. I saw 
there was a website explaining the different functions and their usage 
http://dev.horde.org/ . But, there's no simple example about how to use the 
horde framework for a very very small website: 1 page, with authentification.
   Then I'll be able to uderstand the other functionalities of horde step by 
step...

   Can someone send me a file with such very small piece of code so, I can 
begin to study how thebasic authentification with horde works? I mean a file 
that is nearly independant of any other one but which use the horde framework.

Thanks,
Freeze
