Problem
Where is Python's sys.path initialized from? UPD: Python is adding some paths before refering to PYTHONPATH: ``` >>> import sys >>> from pprint import pprint as p >>> p(sys.path) ['', 'C:\\Python25\\lib\\site-packages\\setuptools-0.6c9-py2.5.egg', 'C:\\Python25\\lib\\site-packages\\orbited-0.7.8-py2.5.egg', 'C:\\Python25\\lib\\site-packages\\morbid-0.8.6.1-py2.5.egg', 'C:\\Python25\\lib\\site-packages\\demjson-1.4-py2.5.egg', 'C:\\Python25\\lib\\site-packages\\stomper-0.2.2-py2.5.egg', 'C:\\Python25\\lib\\site-packages\\uuid-1.30-py2.5.egg', 'C:\\Python25\\lib\\site-packages\\stompservice-0.1.0-py2.5.egg', 'C:\\Python25\\lib\\site-packages\\cherrypy-3.0.1-py2.5.egg', 'C:\\Python25\\lib\\site-packages\\pyorbited-0.2.2-py2.5.egg', 'C:\\Python25\\lib\\site-packages\\flup-1.0.1-py2.5.egg', 'C:\\Python25\\lib\\site-packages\\wsgilog-0.1-py2.5.egg', 'c:\\testdir', 'C:\\Windows\\system32\\python25.zip', 'C:\\Python25\\DLLs', 'C:\\Python25\\lib', 'C:\\Python25\\lib\\plat-win', 'C:\\Python25\\lib\\lib-tk', 'C:\\Python25', 'C:\\Python25\\lib\\site-packages', 'C:\\Python25\\lib\\site-packages\\PIL', 'C:\\Python25\\lib\\site-packages\\win32', 'C:\\Python25\\lib\\site-packages\\win32\\lib', 'C:\\Python25\\lib\\site-packages\\Pythonwin'] ``` My PYTHONPATH is: ``` PYTHONPATH=c:\testdir ``` I wonder where those paths before PYTHONPATH's ones come from?
