Changes in 0.2.0

010820  Append to the logfile rather than overwriting it.
        Released 0.2.0.

010817  Server selection algorithm rewritten in a cleaner, simpler way.
        Blacklist nonresponding servers for a selectable period of time.
        Optional "plain" roundrobin without client tracking.
        (options -b and -r, see manpage).
        Log to syslog if we are running in the background.

010814  Installed pen on siag.nu, which now load-balances itself. Apache
        runs on port 8080, pen on 80. Seems to work (tm).

010813  Added description of options to pen.1 and mergelogs.1.
        Script to guess libraries.

010812  Fixed typo (webmerge -> mergelogs) in pen.1.
