Current Directory structure ?

Hi, I have looked at the current PEAR directory structure in the CVS tree and I don't understand why there are so many Net_... and XML_... directories. Shouldn't these directories be under Net/ and XML/ ? This is unclear to me. I would also like to know why there is no HTML directory in /PEAR. Should I create one or can someone transfer the existing one to the new one ? And finally, are we going to have a global XML file with details on all PEAR extensions (a bit like package.xml) ? It would be easier to create installer client applications and to get details directly from them. Thanks for your replies. Bertrand Mansion Mamasam
