goenv - Set up a Golang environment

I got tired of manually setting my GOPATH when I went from one project to another, so I wrote a small utility to set up my environment for me. It is similar in spirit to Python's virtualenv, though it does less, and does it a little differently.

The main difference is that instead of an 'activate' script that sets up your environment, this opens up a new subshell for you to work in. It will also download and install the version of Go that you want it to.

Installation

Currently goenv is written in python, so installation is a simple pip install away:

$ sudo pip install pygoenv

Usage

$ cd /path/to/project
$ echo $GOPATH

# simplest usage
$ goenv

# You don't have to download a new go tarball every time...
