Mornin',
A few years ago, i got tired of trying to keep my normal configs (bash,
vim, cvs, screen) in sync on all the machines i had shell accounts on,
so i decided to script it. So i defined one set of configs to be the
master set, and wrote a script on that machine to copy the configs to a
list of other machines/accounts. That was fine, except it took ages.
Anytime a machine wasn't reachable (due to it being off, or the ssh
tunnel being down, mostly), everything just hung waiting for the
connection attempt to time out. So i reworked the script to do the copy
to all the machines/accounts in the list at the same time. It also
prints out, every second, a list of the machines that have yet to
complete. In general, it's quite useful, and i thought someone else
might find it useful too, so here it is:

P.s. i haven't actually looked at the source of this in a few years, so
it's possible there are ways of simplifying some of it, but hey, it
works ,-)
