+This command initializes Bugs Everywhere support for the specified directory

+It is usually a good idea to put the Bugs Everywhere root at the source code
+root, but you can put it anywhere.  If you run "be set-root" in a subdirectory,
+then only bugs created in that subdirectory (and its children) will appear
