Added the ability to rename existing pages.
[[!redirects Some Page Name]] redirects Wikilinks [[Some Page Name]] to
the current page (assuming "Some Page Name" does not exist).
Real pages trump redirects (though this may change, depending on
user feedback).
Instiki now runs on the Rails 2.3.0 Candidate Release.
Among other improvements, this means that it now
automagically selects between WEBrick and Mongrel.
Just run
./instiki --daemon
