[PyKDE] Speeing up source file creation when using SIP with PyQt/PyKDE

[Paul Giannaros]

I'm creating bindings for a module in KDE (not included in PyKDE). While 
things work fine, running sip on the .sip file takes a long time on my 
machine -- ~15 seconds. It looks like it's processing all of the Qt/KDE sip 
stuff each time. I don't fully understand the sip system, but is there a way 
I can stop it doing so, and just process my single one? None of the arguments 
to `sip` look promising, neither does a quick search of the documentation 
help.
