.Sh DESCRIPTION
.Nm
is the UNIX version of the SETI@home client. It downloads radio telescope
data from a network server, analyzes the data looking for signals of
extraterrestrial origin, and uploads results to the server, repeating this
cycle indefinitely. See http://setiahome.ssl.berkeley.edu for more
information.

can be freely aborted and restarted. It saves its state in files,
and will pick up where it left off.
.Pp
If you wish
.Nm
to be started automatically, you may wish to setup a cron job. The supplied
script "set_cron_job" will create a script for running setiathome and add it
to your crontab. To use it, change to your
.Nm
directory and type "./set_cron_job" at the prompt. For more information on
cron jobs see the crontab(1) manual page.

.Nm
requires about 0.5\ MBytes of disk space in it's working directory, and about
12\ MBytes of memory. If you have ample physical memory, it's work load
should be almost undetectable.

This port to FreeBSD includes a start-up script (usually found in
.Pa /usr/local/etc/rc.d/setiathome.sh )
that starts
.Nm
at system start-up. You can also use this script to set up a working
directory
.Pa ( /var/db/setiathome ) ,
and lets you register with or login to
