There are some great packages for Exporting buffers to particular formats, but each one seems to reinvent the core mechanism of processing the font-lock in a buffer such that it can be exported to a particular format.
This package aims to produce a versatile generic core which can process a fontified buffer and elegantly pass the data to any number of backends which can deal with specific output formats.
This is very much a work in progress, a rough plan can be seen below. I fully expect some important items to have been forgotten.
