Hmm.. it looks like the json.js code may have been re-released back into the
Public Domain, without the troublesome clause:

    Public Domain.

    NO WARRANTY EXPRESSED OR IMPLIED. USE AT YOUR OWN RISK.

There's also an older version at json.org/json.js, which seems to be PD as
well. In fact, I can't find a copy of the non-free json.js on json.org any
more.

It seems that the API in json2.js is compatible with the current json.js in
jifty. We can probably upload a new package replacing this file with the
newer one from json.org.

Other Crockford software will need checking though (JSLint, JSMin, etc), as
they still seem to be non-free.
