Libmobi

C library for handling Mobipocket (MOBI) ebook format documents. It is in a beta stage currently marked as version 0.1.

There is a simple program included in the project: mobitool.c. It may serve as an example how to use the library.

What works:

reading and parsing:
- some older text Palmdoc formats,
- Mobipocket files,
- newer MOBI files including KF8 format,
- Replica Print files
recreating source files using indices
reconstructing references (links and embedded) in html files
reconstructing source structure that can be fed back to kindlegen

Todo:

reconstruct dictionaries
process RESC records
exporting to EPUB documents
writing MOBI documents
