# configure turns this file into paths.py which is installed in the bin
# directory.  By importing this module, sys.path gets `hacked' so that the
# $prefix/Mailman and $prefix/pythonlib directories are inserted at the start
# of that list.  This file exports two attributes that other modules may use
# to get the absolute path to the installed Mailman distribution.
#
# Note that we can't use site.addsitedir() because that ends up appending
# directories to sys.path and we really need to add them to the front so that
# they override anything in the system Python.
