Update of /home/or/cvsroot/src/or
In directory moria.mit.edu:/home2/arma/work/onion/cvs/src/or
Modified Files:
config.c main.c or.h routerlist.c
Log Message:
if the default torrc isn't there, just use some default defaults
plus provide an internal dirservers file if they don't have one
having no config files will make it easier to run on windows
