timer script

[Chuck Hallenbeck]

Attached is a bash script that counts down by seconds and display the
remaining time on a single line of output. The single argument is the
number of seconds you wish to wait. Remaining time below ten seconds
will be given on each second, below 100 seconds will be given every ten
seconds, and longer waits will be given every 100 seconds.

I am not sure I like it, but it works. Unfortunately it prevents you
from using other arguments than seconds. i.e., not minutes or hours.
