* syslogd can now log messages to a remote host -- patch thanks
to Gyepi Sam <gyepi@praxis-sw.com>
* Rewrite of 'tail' to make it simpler, smaller, and more robust.
- It now weighs only 2.25k (3k when full featured). The code it
- much cleaner, thanks to "Allen Soard" <esp-software@mail.hypermart.net>
