Here is a brief explanation about how to use Monticello with configuration maps for managing updates.
Make sure you have the latest versions of Monticello and MonticelloConfigrations from http://source.impara.de/mc.html loaded.
From the Morphic world menu, choose "open" and "Monticello Configurations" to get an MCConfigurationBrowser.
The MCConfigurationBrowser allows you to add packages as well as an order in which they should be loaded. For this example, let's "Add" a few packages by choosing "match..." and select "Tweak-*". This will get us a list of packages like here:
If there is a need, we can move the packages up and down to achieve proper load order.
We also need to specify where the packages should be loaded from. We do this in the middle pane of the MCConfigurationBrowser by choosing "add repository..." from the context menu. Let's select http://source.impara.de/Tweak.
Now select "Post" from the MCConfigurationBrowser. You will be asked for a name for this configuration - name it just in the way you would name an update, here we will call it "UpdateTest".
From here on, everything goes through the regular updating process. You will be asked which update stream to post it to, (if needed) to supply your password etc.
