[Search-l] why is Wikia's the only frontend? [Was: wrong questions]

[Rainer Blome]

If alternative front ends are desired, the costs of writing them should 
be lowered.  The cost of writing another front end could be lowered by 
copying and modifying an existing front end.  To do this, programmers 
need an appropriate license, which I miss.

Source code for the Wikia Search front end is accessible at

http://svn.swlabs.org/re.search/

In there, I can not find any pertinent copyright or license notices.

Whose code is this (I assume Wikia's, unless otherwise noted).
How is this code licensed?
