It can be run via java Pipeline config-file-name.

The specified config file is parsed using the Apache Commons Digester. This config file specifies an input file to be read, a number of user-defined transform classes to be instantiated and configured from the config file, and an output file.

The contents of the input file is then passed to the transform objects, and the output written to the output file.

Why not try writing your own transform classes, and plugging them in. Note that they can configure themselves from the main config file in any manner the Digester supports, without changing a line of this application.
