Gerben brought the following to my attention: In some occasions  
specifying the wrong or no format or program name yields different  
results (including no results at all). Causes are unclear (to me it  
seems like a bug, but it probably _is_ intended behaviour).

Examples:

$ kpsewhich --format='web2c files' fmtutil.cnf
/usr/local/teTeX/share/texmf.local/web2c/fmtutil.cnf

$ kpsewhich fmtutil.cnf
/usr/local/teTeX/share/texmf/web2c/fmtutil.cnf

And in this case you want the _former_. Sorry for the confusion.

Maarten
