Fork of the original goenv. Fixed for python3 and added activate scripted based on virtualenv from python
Currently goenv is written in python, so installation is not a simple pip install away:
$ sudo pip install git+https://github.com/3m0W33D/goenv.git
$ cd /path/to
$ goenv project
$ source project/bin/activate
# specify Golang version
$ goenv project --go-version 1.1
