Whoops - broke all output :)

More TODO's

Started implementing timers - it does time it - it just does nothing with it :)

Initial version of pjob, a parrallel job runner. (Or Petes job).

Program takes a command, and X arguments. It will run the command with
argument x in parralle, up to Y number of jobs at once. It allows
command substitution, and with an argument file will take several
arguments.

The most basic example is:

pjob -c /bin/echo Azz Pete Tim Fred

This would run '/bin/echo Azz', '/bin/echo Pete' etc etc in parrallel.
A slighltly more detailed example:

pjob -f 'HOSTNAME' -c 'ssh HOSTNAME uptime' myrtle raptor swallow.

This would run

'ssh myrtle uptime', 'ssh raptor uptime', 'ssh swallow uptime' in
parrallel.

A slightly more complex example:

A datafile of:

elm 192.168.0.53 kent.ac.uk
swift 192.168.0.34 ukc.ac.uk
otter 192.168.0.116 ukc.ac.uk

run with the command
pjob -f 'name ip domainname' -c 'adddns -h name -i ip -d domainname' -a datafile

would run

adddns -h elm -i 192.168.0.53 -d kent.ac.uk
adddns -h swift -i 192.168.0.34 ukc.ac.uk
etc etc

pjob be default output all data to the screen with a jobname prefix, and also a [out] or [err] prefix showing
if the output as on stdout or stderr. A stdin file can be specified, and pjob will open this file, and write
its contents into the stdin of the jobs it executes.

Command arguments seem to be a bit unpopular - so may be changed.
