Subject: Re: when a ruby script gets arguments passed to it.....

There is a library distributed with ruby to parse arguments.  As an 
alternative, I have an argument parsing module which I will send to you if 
you like.  I will release it generally when I've completed some 
documentation.  For the one distributed with most linux distros there is a 
program in the ruby examples directory which uses it.

In general, the best syntax (IMHO, of course) is the extract each argument 
from the input list using ARGV.shift.  Other methods for accessing members of 
a string array can also be used.
