+Because Python is interpreted, when you look at the task manager / process list
 you'll see that every running python instance has the same name, python.exe.
-This scripts helps you name the executables so they stand out.
+This script helps you name the executables so they stand out.
 
 For the time being this script doesn't automatically call your new exe, you
 have to write a second command to actually run it. I tried using
 subprocess.Popen to spawn the new python with the rest of argv but the behavior
 was different on Linux and Windows and neither was really clean.
