                                           ComputedCore

A core wrapping external applications.

ComputedCores wrap command line tools taking command line arguments, reading from stdin, and outputting to stdout.

The command line arguments are taken from the inputTable's parameters, stdin is created by serializing the inputTable's rows like they are serialized for with the TSV output, except only whitespace is entered between the values.

The output is the primary table of parsing the program's output with the data child.

While in principle more declarative than PythonCores, these days I'd say rather use one of those.
