Things to do: - Write documentation for how to use libstemmer (as opposed to how stemming algorithms themselves work). Currently, the documentation in the include/libstemmer.h header file is pretty clear and comprehensive, but an overview document wouldn't go amiss. Things that would be nice to include at some point. - Add version numbers to each stemming algorithm, and allow the interface to request a specific version of the stemming algorithms. Default to providing the latest version of the algorithm.
