Doug Barton 989772c9ac The vast majority of pkg-descr files had the following format when they
had both lines:

Author: ...
WWW: ....

So standardize on that, and move them to the end of the file when necessary.

Also fix some more whitespace, and remove more "signature tags" of varying
forms, like -- name, etc.

s/AUTHOR/Author/

A few other various formatting issues

ttlscan is a libnet/libpcap based program that sends a TCP SYN packet to
each port of the host given via the command line. The answer is sniffed
of the wire. I use it to detect hosts that fake services by forwarding
packets to another host (behind a firewall). By reading header files
like the TTL, window size and IPID you might be able to see the OS
running on the host behind the firewall.
