featlib.cpp	Example feature extraction code: computes the fraction of dark pixels.
featlib.h	Header for featlib.cpp
featlib.i	Interface between C++ and Python for featlib.
lxj-coding.table	Table with lxj-encoding for text characters.
lxj-convert.py	Uses lxj-coding.table to convert text to lxj encoding.
Makefile	Description how 'make' should compile the code.
pamImage.cpp	Read and write .pbm/.pgm/.ppm files (color, grayscale, black/white respectively).
pamImage.h	Header for pamImage.cpp; look here to see what you can do with a PamImage object.
pamImage.i	Interface between C++ and Python for pamImage.
wordio.py	Reads and writes .words files.
word.py	Object for word zones and transcription.
lxj-convert.py	Converts strings to lxj encoding.

The .i files define an interface between C++ and Python. Swig uses them to create a Python wrapper around the C++ code.
