File generator tool (FMPP)

FMPP is a command-line tool, Ant task, and embeddable library, for generating text files. The files are generated directly by processing FreeMarker template files, and/or by processing (transforming) XML files with FreeMarker templates. It can process whole directories recursively. It allows templates to split their output into multiple output files.

Note that the FreeMarker download already includes a light-weight Ant task specialized on transforming XML files with FreeMarker templates. FMPP can do it too, but as it is more heavy-weight and more general purpose, it's harder to learn using it.
