+This extension is deprecated. Rather than using this extension

+The builtin [websub] section supports the same syntax as the interhg
+extension. The difference is that where interhg would apply the
+replacement expressions on all the hgweb output, the websub patterns
+are only applied to full changeset descriptions. In addition the
+websub expressions can be different for different repositories.
