# The "inputs" array defines the structure of the input object that describes
# the inputs to the underlying program.  Here, there is one input field
# defined that will be called "input" and will contain a "File" object.
#
# The input binding indicates that the input value should be turned into a
# command line argument.  In this example inputBinding is an empty object,
# which indicates that the file name should be added to the command line at
# a default location.

# The "outputs" array defines the structure of the output object that

# output.txt in the designated output directory.
