There used to be some documentation in the Nitpick manual  
(nitpick.pdf), but nowadays Kodkod(i) is shipped with Isabelle, so the  
problem only arises for adventurous people (i.e. developers). If you  
grep for MISSING in

http://isabelle.in.tum.de/repos/isabelle/file/edd50ec8d471/doc-src/Nitpick/nitpick.tex

you'll see some instructions.

And if you try running "nitpick" and Kodkodi isn't installed, you  
should get this message (from "nitpick.ML"):

    182 fun install_kodkodi_message () =
    183   "Nitpick requires the external Java program Kodkodi. To  
install it, download \
    184   \the package from Isabelle's web page and add the \"kodkodi- 
x.y.z\" \
    185   \directory's full path to " ^
    186   Path.print (Path.expand (Path.explode "$ISABELLE_HOME_USER/ 
etc/components")) ^
    187   " on a line of its own."

(from http://isabelle.in.tum.de/repos/isabelle/file/edd50ec8d471/src/HOL/Tools/Nitpick/nitpick.ML) 
. Now, Kodkodi doesn't seem to be available from the download page  
anymore, but you can get it from my home page or steal it from NFS.  
Version 1.2.16 works fine. (I really need to update the above message!)

It should have caught the above message, though. ;)

Cheers,

Jasmin
