;;;   THIS IS EXPERIMENTAL AND DOES *NOT* WORK
;;;
;;;  Koskenniemi-style context rewrite rules for English Morphographemics
;;;  Basically splits words into their (potential) morphemes.
;;;
;;;  Based (roughly) on the rules in "Computational Morphology"
;;;  Ritchie et al. MIT Press 1992.
;;;
;;;  This is not a Scheme file and can't be loaded and evaluated
;;;  It is designed for use with the wfst tools in the speech tools
;;;  e.g. wfst_build -type kk -o engmorph.wfst -detmin engmorph.scm
