Console helper to set Go(lang) path variables from current directory using `gopath`

godev.sh

#!/bin/bash
#---------------
#
# Installation:
#    $ curl -Lo ~/.godev http://tiny.cc/godev
#    $ echo "source ~/.godev" >> ~/.$(basename $SHELL)rc
#
# Usage:
#    # Tries to determine go workspace directory, then
#    #   exports it into GOPATH environment variable
#    $ gopath
#    
#    # Creates a new go workspace, including all sub-directores
#    $ create-go-project github.com/mee/myapp
#---------------
