/* This quick hack can be used to generate Product-Info files from a typical
"Contents" file. It creates subdirectories in the current directory,
one for each "Product" found in the Contents file (and with the same name),
and generates a Product-Info file within that directory.
This code is Public Domain. -Fred Fish
