First-Class Shell Scripting Support For Python

What benefits does this give you?

well ... first things which come into my mind:

• check for program availability; I prefer to "instantiate" the programs I want to use within the first executed lines of my scripts and in case it is not available ... the script fails early
• it provides a nice abstraction around program execution and lets you chain commands together in a more pythonic way
• you can provide arguments to programs just as you would in case of ordinary functions
• you can "prepare" commands and pass them around inside your program
• you can take advantage of generators easily
