Well, we know that frequently the mirror(s) we use are bad, because
after we rsync from them to a local disc for use on our intranet, it
fails the MD5 checks of the files. I wrote this script to make the
check nightly, after the rsync.
I just wish all the mirrors did this routinely, so we didn't need to
discover it after the rsync.

USAGE="Usage: $MYNAME [-q] [--record] [cygwin-mirror-directory]
Where:
-q means quiet.
--record means record a success or failure indicator in the
the directory above the mirror directory, by making
$CYG_GOOD & $CYG_BAD files
appear or disappear (so even DOS batch scripts can test
the archive's goodness).
You have to have write permission for this to work.
cygwin-mirror-directory
this should be the directory where you find setup.bz2,
setup.exe, and setup.ini.
Success/failure files are created in the directory
above this, if the --record option is used.
Defaults to /u/mirror/cygwin/release.
E.g.:
$MYNAME --record -q /u/mirror/cygwin/release
NOTE: running md5 over 2GB of files is best done on the host
machine, to avoid hammering our network.
(Use 'df -k \$MIRROR' to discover what machine
hosts \$MIRROR, that you should slogin to,
to run this $MYNAME.)"
