# VVV Site Setup Script
# By Alison Barrett <alison@barre.tt>
# https://github.com/aliso/vvv-site-wizard
#
# Version 1.0
#
# This script automates the creation & deletion of new WordPress sites using
# Varying Vagrant Vagrants (https://github.com/Varying-Vagrant-Vagrants/VVV).
#
# Usage:
# vvv new|create|make [site]
# vvv delete|rm|teardown [site]
# vvv list
# =============================================================================
#
# When not called from the VVV root directory, the script will prompt the user
# for the path to VVV. To run this from any directory and skip that prompt,
# uncomment the following line and set it to the VVV root dir:
# path=~/VVV/

# =============================================================================
# Helper function for printing out usage information.
# =============================================================================
usage() { echo -e "Usage: vvv new|create|make [site]\n       vvv delete|rm|teardown [site]\n       vvv list"; exit 1; }

# =============================================================================
# Helper function since a green "Done." is used in a lot of places
# =============================================================================
done_text() { echo -e "\033[32mDone.\033[0m"; return; }

# Helper function to make colored text easier to code and more readable
