way too freaky.... it works... but I am having
problems with the verification - since I just
ran this against an od -c /usr/local/bin/perl
and I find places in it in which there are instances
of "/usr/local" that do not show up as "/tmp/local"
in the version I just created with the above....

I am now officially WAY confused here....
When I first read your response John - i thought to myself,
"Oh dear - this must be one of those Win32 things,
that I have not taken the time to read about...."
then I find out that SAGE is an extension of the usenix organization
- The System Administrator Guild -
hence that the reference to 'binmode' here is not going to be of
much use to the typical usenixy.....
At which point I go back to my initial emotional crisis - namely
MY GOD MAN! THE DAYS OF PATCHING EXECUTABLES WITH SED.....
