Bootstrap a Flask project

mkflask.sh

#!/bin/bash -e

# opinionated Flask bootstrap script
# assumes you'll be using MySQL, Fabric, and Blueprints
# creates a virtualenv and an Alembic migrations system
# The script will halt on any error, and remove the project dir if it created one
# accepts a single argument: a new directory name under which to create the project

# check that Python is installed
type python >/dev/null 2>&1 || { echo >&2 "Python doesn't appear to be installed. Aborting."; exit 1; }
# check that there's a system-wide virtualenv package installed
type virtualenv >/dev/null 2>&1 || { echo >&2 "This script requires a system-wide install of Virtualenv. Aborting."; exit 1; }
