v 0.5, 2001/10/10

1) Renaming of all glyphs

	All glyph identifiers used in ligtables etc. are now
	renamed according to the LH conventions.

v 0.3, 1998/12/15

1) New Glyph: Currency Sign

	The Mongolian togrog (aka tugrik) was added. The symbol is a
	double-barred sans serif T or t but I decided to include
	serif versions as well, and in lower case and upper case,
	for those who love choice.

v 0.2, 1998/06/01

1) Font Names

	The whole font set was renamed according to the CM
	tradition (for easier diagnostics of missing and/or 
	unmatching fonts between Latin and Cyrillic).

	Read KM (substituting CM in the font names) as
	"Komp`yuter Modern" (Mongolian for Computer Modern)
	or
	"Kirill Mongol" (Mongolian Cyrillic)


2) Font Shapes

	More fonts from the Computer Modern Family were added:
	Dunhill, Variable Width Typewriter Text (also Italic);
	Funny (both Upright and Italic).


3) Path Errors

	Some font source behave strangely in combination with
	certain parameter files; in particular, it was necessary
	to tune de, De and ze in the Cyrillic sources.

v 0.1, 1997/10/01

Changes involved for creating mcyr (Mongolian Cyrillic)
on the basis of cmcyralt

1) Font Encoding

	The encoding definition file was rewritten in order
	to accommodate for LMC (Local Mongolian Cyrillic)
	encoding. This is basically a transliteration mirror
	of T1 (Cork) encoding, with Mongolian front vowels in
	the appropriate T1 umlaut slots.

2) Internal Character Names

	CYR_HA ("X") and CYR_ha ("x") were changed to CYR_XA
	and CYR_xa throughout all occurences of all files  in
	order to accommodate for the Buryad letter which looks
	(and is pronounced very much) like a "h".

3) Glyph Shapes

	The front vowel CYR_OE/CYR_oe was taken from J. Knappen's
	Bashkirian sources; so were CYR_UE and CYR_HA/CYR_ha.

	CYR_HA had a strange path error when used in italics mode;
	one angle of a penpos was changed from 90 to 95 degrees
	which resolved the problem without distorting the result
	visibly.

	CYR_ue was given as a gamma by J. Knappen which is not
	acceptable; CYR_ue is a letter with a high frequeny so
	reading the gamma would be quite irritating. Besides,
	a proper gamma is used in transliterations. A new CYR_ue
	was thus designed.

4) Conventional Glyphs

	More glyphs (digits, punctuation, etc.) of the original
	cmr sources were included in order to decrease the amount
	of font switching in mixed-language documents.

5) Ligatures

	A set of constantly active ligatures was introduced which
	takes care of some of the Cyrillic umlauts as well as
	"sh", "yo", "ya" etc.

6) Font Names

	Everything was renamed properly so as to avoid collisions
	with existing cmcyralt installations. A notice to that
	effect was prepended to every file.

7) Internal Clean-ups

	The parameter files are paragons of a Write-Only coding
	style; just for the modifier's own convenience, some 
	tabbing was inserted here and there, without any functional
	effect, of course.

	Some of the commands which are leftovers of the original
	cmr sources (from where everything is derived) and which
	do not make any sense in this encoding were simply deleted
	for sake of a better readability of the file.
