New Revision: 15444

Modified:
   torflow/branches/gsoc2008/TorCtl/PathSupport.py
Log:
class SelectionManager has been updated to include the variable 'restrict_guards_only'. When this is equal to True, PercentileRestriction will only apply to entry nodes. This is achieved through changes to SelectionManager.reconfigure().

class Connection has been updated to include an __init__ function. It calls the init function for TorCtl.Connection.
