Webrev lets you create comparisons based on directly specified file lists, it
doesn't even need the sources to be in an SCM. This means we can create
webrevs between arbitrary directories, as long as we spell everything out by

You make your changes in

Webrev will create a webrev showing files being renamed from their path in the original source to their path in our source, and diffs between the two sources, as if both were part of the same source tree.
