# configure.sh - Setup your OpenBazaar development environment in one step.

# If you are a Ubuntu or MacOSX user, you can try executing this script
# and you already checked out the OpenBazaar sourcecode from the git repository
# you can try configuring/installing OpenBazaar by simply executing this script
# instead of following the build instructions in the OpenBazaar Wiki
# https://github.com/OpenBazaar/OpenBazaar/wiki/Build-Instructions

# This script will only get better as its tested on more development environments
