- IsOn's purpose is to let you know when someone logs on. You could always sit
- there at your terminal typing 'finger' or 'who' every 5 minutes, but that's
- boring and unproductive. IsOn makes this easy. If you wanted to know the
- instant I logged on, all it would take is a simple:
-
- ison mgleason@cse.unl.edu
-
- When I do log on, ison would respond:
-
- ** mgleason logged in since Wed Oct 16 02:19:33 1991

- IsOn lowers it's priority automatically, so it takes very little CPU, and
- spares you the trouble of remembering to use 'nice.' It also puts itself
- in the background automatically, as of version 4. For remote addresses
- (those in dude@machine.domain format) the 'finger' utility is used, or for
- a user on the same machine that you are on, IsOn will simply walk the 'utmp'
- file.

- Version 4 changes:
- + Auto-backgrounding.
- + Optional -a flag will prompt for a username (to hide from ps :-)
- + Default remote delay is longer, to ease the load on the network.
- + Quits when finger times out or barfs.
- + Quits when parent is killed (logout, hangup, etc).
- + Should compile without incident on SunOS.
- + Obscure bugs fixed.
-
- Enjoy!
