#
# Conduit is an application based on the Rocket web framework.

# is in this file) and optionally by uncommenting and tweaking the variables in
# /etc/matrix-conduit/local.
# THIS FILE IS GENERATED BY DEBCONF AND WILL BE OVERRIDDEN!
#
# Please make changes by running:
#
# \$ dpkg-reconfigure matrix-conduit
#
# or by providing overriding changes in /etc/matrix-conduit/local.
