This is [[pson]], a Rubygem for converting (some) Ruby objects
into the (hypothetical) PostScript Object Notation.  Numbers,
strings, symbols, arrays, hashes, and Boolean values are
supported.

You can convert a supported object by calling the
[[to_postscript]] method, and the recursive converters (for
lists and dictionaries) follow this protocol, too.  Thus, if you
should implement, say, PostScript transformation matrices,
paths, or code blocks by defining a new Ruby class, you can
provide a compatible conversion mechanism by implementing the
same method.

Note that there's no matching parser.
