/**
* Updates a Buckminster rmap (XML file) from a B3 build model. The rmap is updated using
* comments in the XML that reference the model elements from which the update sites must be copied.
* <p>
* These comments must appear before each "rm:uri" element which must be updated automatically, like this:
*
* <pre>
* <!-- updateFrom("Eclipse", 0) -->
* <rm:uri format="http://download.eclipse.org/eclipse/updates/4.2milestones/S-4.2M3-201110281100"/>
* </pre>
*
* The first parameter in updateFrom is the label of a contribution, which you can find in the b3aggrcon files:
*
* <pre>
* <aggregator:Contribution ... label="xxx">
* </pre>
*
* The second parameter is the index of the "repositories" element that must be used (in case there are several update sites defined on one contribution).
