+#!/bin/sh

+#when forking a repo from github, one might need to mask imports in a package
+#this scripts checks for the existence of a local package with the same name
+#and links/unlinks the remote into the local. 
+#so let's say that you fork on github https://github.com/foo/bar and you are baz.
+#you would git clone git@github.com:baz/bar.git but it would contain all the upstream imports
+#using this scipt you will be able to fool your go installation to point them to your local copy.
+#by doing: gogithub mask foo/bar 
+#and restoring it by: gogithub unmask foo/bar
