! This automaton hyphenates Turkish words. In Turkish,
! hyphenation is always done on syllable boundaries, and the
! rule is regular. The automaton below is based on a "textbook
! case" replace operation. The only complication comes from
! the fact that there can only be a single vowel in a syllable
! (it happens only in few foreign-origin words). We first make
! sure that all vowels are split, and then insert a hyphen
! after a C*VC* sequence, if precedes CV. Apostrophe is
! ignored.
! 
! The automaton seem to work fine (not tested extensively, but
! used for a few practical cases). Only known (potential)
! problem is related to how words like 'elektrik' is
! hyphenated. Following the general pattern the automate will
! hyphenate it as e-lekt-rik, although one may consider the
! syllable boundaries to be e-lek-trik.
