generation of online php documentation

Hi,

I'd like to learn the way the online php documentation is generated from the xml sources. 

I'm a little bit confused because I've found several entries in the CVS tree where I might find the actual scripts doing this task; like "docstuff", or "docweb", and the "phpdoc" module is there either. 

Could you tell me please, what exactly should I checkout from the cvs? (I have a slow modem connection, this is why I try to figure out this instead of downloading all and browsing through...) Or how can I get more info about this? 

Sorry if I ask this in the wrong place, any pointer is gratefully received.
