How to import a plugin from before the subtree merge

So, you want to import a plugin written before the Big Subtree Merge. Here's how to do it :

1. Add a medInria-plugins remote on your medInria repo :

git remote add plugins https://github.com/medInria/medInria-plugins.git

2. Add the remote of your fork :

git remote add plugins-bob https://github.com/bob/medInria-plugins.git

3. Switch to your plugin branch :

git checkout bob/my-plugin

4. Rebase this plugin on the medInria-plugins master branch :

git rebase plugins/master

5. Now the bit of magic, rebase your plugin onto the medInria master :

git rebase -s subtree master

And that should be it !
