make_butter.sh

#!/bin/sh

## Version 0.1.1
##
## Usage
## ./make_butter.sh [url]
##
## The script make_butter.sh allows you to clone, setup, and build a version of Butter
## The [url] handle is optional and allows you to pick what repository you wish to clone
## If you use 'ssh' in the place of the optional [url] parameter, it will clone via ssh instead of http
##
## Optionally, you can also pass in a specific branch to build or clone, by making url contain a branch specifier
## ./make_butter.sh '-b release/0.3.4 https://github.com/butterproject/butter-desktop'
