Another "rival" piece of source code you might want to look at is within
my "jbofi'e" program, available at
http://www.rrbcurnow.freeuk.com/jbofihe.  There is an algorithm of sorts
within the split_lujvo function in canonluj.c for breaking lujvo into
constituent rafsi.  This algorithm is pretty lax about whether consonant
clusters etc are valid or not.  It assumes the "lujvo" it has been given
to break up is valid in the first place.   To do the legality checking
(in the early stages of processing the input), a fairly complex
automatically generated state machine is used - see morf.c, morf_nfa.in
and the builder sources in the n2d subdirectory.  BTW, a new release is
hopefully going to appear quite soon now.
