wanted: C long name fudger

[Mark Mendel]

This is NOT part of the misplaced long name debate. This is an honest request!

Does anybody have a program the crunches down long names automatically?  I've
read articles where the use of such
a program was recommended, but does it
exist?  I'ld like a copy!

A good method would be: 

all names longer than n (a command line paramter) are transformed as follows:

    xy...z -> xNNNNy...z,

    where NNNN is the base 36 representation of a the hash function of the full
    original name, say a 16-bit crc.
