bootstrap.sh

#!/usr/bin/env bash
#
# This bootstraps smash, eventually running smash's install.py and setup.py
# Why not just run setup.py directly?  Smash should be installed in a private
# virtual environment (not shared between users).  This venv needs to be setup,
# and before install.py can actually be used, install_requirements.txt must be
# installed.
#
# The bootstrap command accepts a single argument, which is the smash branch to
# use.  If the argument is not given, it defaults to master.  Alternatively, you
# can set the SMASH_BRANCH environment variable, for instance if you're invoking
# this bootstrap with curl:
#
#  $ SMASH_BRANCH=master
#  $ bootstrap=https://raw.githubusercontent.com/mattvonrocketstein/smash/$SMASH_BRANCH/bootstrap.sh
#  $ curl bootstrap|bash
