            switched.

            fonts. Renamed tcr -> tcrm, tcb -> tcrb, tcu -> tcui.

22-DEC-1996 Got rid of txmacros.mf by moving the few definitions either
            to exbase.mf or txaccent.mf.
            Consequently applied |hi.| in txpseudo.mf.
 
20-DEC-1996 Starting transition to ec: Renamed files, replaced |dcchar| by
            |ecchar|, changed file headers, changed |version_check| to ask
            for (1,0).

            servicemark, abzueglich

18-NOV-1996 Added more characters: textminus, ascender height cwm,

            numero sign, aestimated sign, quill brackets,
            reference mark, textsurd, open bullet

18-NOV-1996 Applied the changes in dcbi parameters also to

23-AUG-1996 Changed Parameters for tcsx at 5 pt.

23-AUG-1996 Added |zero_width| to the programme for the capital compound word
            mark; without this statement the chardx value is wrong.

*********** Release of dc 1.3 **************************************************

31-MAY-1996 Corrected |tiny| for dcsx..tcso at 5 pt
            Changed |clear_memory| to |clear_extra_memory|

            Removed unneeded |lc_circle_height(#)|

            sizes (14.4 instead of 14 etc.)
            Buildt in version consistency control
            Added comma and full stop to the tc character set,
            this facilates macros for oldstyle digits.

            consequences
