These aren't part of core Allura for licensing and demonstration reasons, but would be good to keep maintaining them.
TracWikiImporter doesn't have much test coverage, and doesn't get used much at all. Main Allura codebase has a test that uses it: forgeimporters.trac.tests.functional.test_trac:TestTracImportController
forgepastebin,tracwikiimporter,allura:db/8382
Need to do releases and version bumps. I found
http://www.cansas.org/trac/wiki
as a small real trac instance you can test importing from.tracwikiimporter/scripts/wiki_from_trac/loaders.py
,Those are intentional yes :)
