After a little stalling due to various people lacking free time the Lucene4c project has started to move into the ASF Incubator.
Of course, the status page is already a bit out of date, but I'm sure it'll be updated soon.
Still on the TODO list are bug tracking and a mailing list, but hopefully those will get finished up in the next few days, and I'll be able to return to writing code and recruiting developers instead of bugging people about moving things along in the ASF infrastructure world.
Oh, and as far as actual progress on the project itself I got the beginnings of the query and scorer code sketched out, to the point where I can now search for documents that contain "foo" and "bar". Support for or and not will hopefully get fleshed out soon.
