This document contains both the libabw API specification and the normal libabw documentation.
The external libabw API is provided by the AbiDocument class. This class, combined with the librevenge::RVNGTextInterface class, are the only two classes that will be of interest for the application programmer using libabw.
If you are interested in the structure of libabw itself, this whole document would be a good starting point for exploring the internals of libabw. Mind that this document is a work-in-progress, and will most likely not cover libabw for the full 100%.
