-% Copyright (C) 1997, 1999, 2001, 2002 Claudio Beccari
-% file cbaccent.mf v.2.0f 2001/04/09
-% Added cap-cedilla and sloping sides of nexus 2001/02/25
-% modified circumflex for the cbleipzig fonts 2001/04/22
-%
-% The accent macros that follow are used by all the vowel macros for
-% generating the ligatures; they mostly come from Computer Modern.
-%
-% CB added the tests on boolean monotoniko whose value is set either by the
-% driver files or it is false by default. Fixed the currentbreadth problem,
-% and changed several dimensions so as to work well with different parameter
-% settings.
-%
-% Several accents were completely redesigned, in particular grave and acute
-% and their combinations with diaeresis or breaths are such that do not
-% change according to the letter they accompany; in a different way
-% also the circumflex and the diaeresis have been modified accordingly.
-%
-% Booleans monotoniko and toniko are remains of a previous test version
-% where the monotoniko accent was the single one for modern Greek designed as
-% a vertical stroke; thanks to Apostolos Syropoulos this feature has been
-% eliminated.
-% (1999) CB added definitions for adscript iota to be used with upper
-% case Alpha, Eta and Omega, and for the corresponding small cap variants.
