FWIW, I have been using a script based on the "sed" command.
I got the script from some book or ftp site, unfortunately
not recorded in the header, and it runs on Cygwin with my
AT&T Korn shell -- not sure why, maybe because of the syntax
for declaring functions?
The only problem I have had with this script is that if a
target filename already exists, that file will be overwritten.
