// Converting complex objects into a simple, clear string that can be appended
// to the swf as a query: myMovie.swf?flashvars=foo.

// Therefore this is something of an "internal" class - unless you know how to
// modify or create SWFs.
//
// description:
// JSON could be done, but Deft does not yet have a JSON parser, and quotes are
// very problematic since Flash cannot use eval(); JSON parsing was successful
// when it was fully escaped, but that made it very large anyway. flashvar
// serialization at most is 200% larger than JSON.

// Deft/common/flashVars.as
