- ``empty`` - The opposite of ``not_empty``. Equivalent to ``(not (not_empty
X))``. Provided for convenience.
+ - ``single_input_file`` - Returns true if there was only one input file
+ provided on the command-line. Used without arguments:
+ ``(single_input_file)``.

+ - ``multiple_input_files`` - Equivalent to ``(not (single_input_file))`` (the

- ``default`` - Always evaluates to true. Should always be the last
test in the ``case`` expression.
