in reply to Wrap multiple programs

You can not get command line options twice within the same program. I recommend writing both Plot and Calc into subroutines within the main script, and go from there.

Otherwise, create a module out of both of the mentioned "things" into modules, import them into your main script, then distribute the cli arguments appropriately.

To the OP: Although below I'll show a way to put multiple commands on one command line, I actually don't necessarily recommend this, nor would I recommend building a monolithic "one script to do it all", instead follow stevieb's and Athanasius's advice to modularize. One element of the Unix philosophy is to make each tool "Do One Thing and Do It Well". If your scripts need to share common functions, then do that through a module, rather than shoving all the code into one script.

You can not get command line options twice within the same program.

That statement is just a little too absolute for my tastes, it's totally possible to get too clever with @ARGV :-)
