'''
The script will only work with python 2.6.x or higher, but not with 3.x

This is a little script wirtten to read a host statistics file made by a boinc project.
It will find out how many logical cpu cores are considdered active (by a threshhold you can define for the "expavg_credit" value)
parameters are given over command line input.

Sorry this is really dirty and not clean writing at all...
