# Helper script for building Debian packages
#
# FreeSWITCH will be downloaded from Git into ./freeswitch/ and built.
# The resulting Debian packages will be placed in the current directory.
#
# You should run this as an unprivileged user, with sudo permissions
# to install build dependencies (add your user to the sudo group).
#
# Build dependencies:
# $ apt-get -y install git dpkg-dev devscripts sudo
# All other dependencies are installed by the script.
#
# If modules.conf exists in the current directory then it will be
# used to select the modules to be built.
#

# Configuration
BRANCH=v1.2.stable
DCH_DISTRO=UNRELEASED
# SIGN_KEY= (Optional)

# Download FreeSWITCH
git clone -b $BRANCH git://git.freeswitch.org/freeswitch.git
