coding for standard in

[tgate]

This is a bit of a newbie question I suppose.

I want to create  command line program that will accept "standard in"  
for arguments.  I want to be able to make my program scriptable so  
that a script looks something like...

______
#!/usr/loca/bin/myProgram

scriptArguments here
______

or from the command line...

% myScript.txt > myProgram

or

% cat myScript.txt | myProgram

I'm not really sure how to go about this.  Should I be using the  
NSFileHandle class somehow?
