Roughly right. However, there isn't any real 'mapping' between packets
and pages. The ogg specifications defines what pages are, and how packets
get framed into pages, but doesn't define anything about how that mapping
should be done (i.e. choices of packets-per-page, page size, etc. are
not defined), and it isn't really specified by the encoder either - the
encoder chooses to use a particular set of parameters, but has no need
to fix those or specify them in other ways.

I'll have a read later - thanks for doing all the work with this.

Hopefully Monty will take a look through this at some point.
