[Twisted-Python] new to twisted

[m. smadi]

hi;

i was writing third party sip call controller when a friend suggested i 
use twisted.  I think it will save me a lot of time, but i had trouble 
with the following when installing:
cvs the pserial and pcrypto required package.  the cvs server complians 
about a wrong password (any hints)

i continued without these package and installed using setup.py.  Where 
is a good place to start (the tutorial provided is not really very 
great) - any other suggestions?
