The first tier of information is:
http://www.riverbankcomputing.com/static/Docs/sip4/index.html
of course. Any sane distribution should have installed this under 
documentation somewhere, e.g. in my openSUSE packages:

/usr/share/doc/packages/python-sip-devel/doc/html/index.html

Another pretty enlightening source is sipdistutils.py. If that's still 
lacking, get all what you want to know (and probably much what you 
don't) by studying siputils.py and the function generate_code in 
configure.py of PyQt. Running the latter in verbose mode is a good 
starter in that quest..
