Crack.exe - help finding author?

Among the various crypto utilities I've picked up off the net, over the
years, is a simple substitution solver called "crack". It's a dictionary-
based matching program, rather than a heuristic keysearch. It's
something like George Hart's approach in Sept 94: "To Decode Short
Cryptograms".

But it's not Hart's code (or rather, it's not Jian Wang's code, who wrote
the code for Hart) - because I have that, too.

Unfortunately, there is no author information in the files I have. What
there is a file_id.diz, containing the following description:

crack lists all the possible solutions

to a simple substitution cryptogram

that are composed of words from a given

dictionary. Only letters and apostrophes

may compose the words. Upper and lower

case letters are assumed to be equivalent.

Anyone familiar with this? Any idea as to who wrote it?

I could climb the very highest Himalayas,
be among the greatest ever tennis players,
Win at chess, marry a princess,
or study hard and be an eminent professor.
I could be a millionaire, play the clarinet, travel everywhere,
learn to cook, catch a crook, win a war and write a book about it.
I could paint a Mona Lisa, I could be another Caesar,
compose an oratorio that was sublime,
The door's not shut on my genius, but
I just don't have the time.
