   1 """terminalcommand.py -- A minimal interface to Terminal.app.
   2
   3 To run a shell command in a new Terminal.app window:
   4
   5     import terminalcommand
   6     terminalcommand.run("ls -l")
   7
   8 No result is returned; it is purely meant as a quick way to run a script
   9 with a decent input/output window.
