Utility to call any system command from python.

Import any program that's on your PATH from ``syscmd.cmds`` and you'll get a
function that executes the program with the given positional arguments. By,
default, the function uses ``subprocess.check_call`` to execute the program. But
this can be changed by passing in one of ``syscmd.CALL``, ``syscmd.CHECK_CALL``,
or ``syscmd.CHECK_OUTPUT`` as the ``f`` argument to your function to get the
respective ``subprocess`` function. Expect the same behavior from the imported
``syscmd`` functions as the ``subprocess`` functions, eg. return value, standard
in/out/error, etc.

In addition to the positional arguments and ``f``, the imported functions also
accept all the keyword arguments of the underlying ``subprocess`` functions.

Examples::

  # Import various system commands
  >>> from syscmd.cmds import echo, ls, true, false

  # Run 'echo' with three positional arguments; stdout goes to stdout and the
  # exit code is returned
  >>> res = echo('one', 'two', 'three')
  one two three
  >>> print res
  0

  # Run 'ls' with no arguments
  >>> res = ls()
