Description: |
If you just downloaded 4.4-install.iso also known as FreeBSD 4.4 ISO, and you "burned" it to a cd, and you wish to make sure that all the packages contained are as they should be (Debian has been really lame about this, I had at least 5 packages fail, even tough the "burn" was good, it turns out, just a shabby iso release)
perl verify_freebsd.pl -d D:/>burnt
WHAT?!?!: For some reason, in \XF86336\CHECKSUM.MD5
the line
MD5 (Servers) = edc0aef739c1907144838e6c18587e02
which apparently is the md5 sum for the "directory" \XF86336\Servers which you might be able to do in *nix, but on on winblow. |

Hello and welcome to Verify Your Debian Potatoe.
This tool relies on the md5sum.txt file
being in the root "directory" of said cd,
and the sums there being correct.
Usage: perl $0 [-?hvd]
-? same as below
-h prints out this message
-v bees verbose (FAILED sums are reported by default)
-d /path/to/cd/a/must
