****** Version 2.11, 30 November 1991
    1) Minor changes, mainly break up package into two parts:
       itrns211 and itrnsps, where itrsps contains the printer
       ready postscript documentation. (ZIP or ZOO format archives.))
       This is in anticipation of downloading to IBM-PC archives, such
       as SIMTEL, etc.
    2) Fixed bug to allow \kern command in PostScript mode too..

****** Version 2.10, 14 October 1991
    0) Major features: IFM file added for Frans Velthuis's devanagari
       font (it is called Devnag);
       lots of new ligatures added to the Devnac PostScript font.
       Ligatures can now be inhibited by using the characters {}
       between two consonants in the input text.
       All ra-<consonants> can now be printed using the hindi form
       (before 2.1 these ligatures were not automatically handled,
        users had to use the special .r to get what they needed.
        From 2.1, the correct form will be used.)
       Marathi users can use alternate IFM files, which use the
       marathi form of ra-half.
    1) A few codenames (internal IFM file format data) changed to
       better reflect the actual character represented.
       This does mean that all pre 2.1 release itrans IFM files are now
       obsolete and incompatible with this and future releases.
       Also made a change in the way PCC .. dx dy works, for details
       see the file tech.tex.
    2) Finally have a better understanding of the archiac vowels (Ri, RI, Li
       and LI). Therefore the old naming scheme (RI RU LI RU) thrown out.
       RI in the old scheme is Ri in release 2.1
       RU in the old scheme is RI in release 2.1
       LI in the old scheme is Li in release 2.1
       LU in the old scheme is LI in release 2.1
       The Devnac font only had the Ri character, it was called
       RU earlier (pre 2.1).
       The Devnag font (Frans Velthuis's) uses all four of the above vowels.

****** Version 2.0, 26 August 1991
    0) Thanks to the following persons for many of the bug fixes and
	suggestions: Samir Agarwal, Madhu Deshpande, Gary Thrapp,
	Vick Khera, and many others.

    1) With the help of Sriram Tyagarajan, added support for Tamil.
       Uses the Washington Tamil font, it was created by the Humanities and
       Arts Computing Center of the University of Washington, USA.

    2) Because of 1, and other changes to support multi-languages,
       new keywords have been introduced:
       \indianifm=xxxxxxx   %% set the current IFM file
       There is the concept of a current IFM font file, which contains
       the font data used to construct indian language characters.
       All \marathi or \hindi or \tamil do is to mark the beginning of
       the transliterated text, they do not load in any IFM files, all
       loading must be done thru the \indianifm command.
       \indianfont=yyyyyyy %% command that will printed at \hindi
       See idoc.itex for more info.

       (Old documents with \marathi etc will still work since the default
	IFM file loaded in is devnac.ifm --- the hindi/marathi font
	metric file.)

    3) Changed file extension .itex to .itx, and changed name of file
       devnac.text to devnac.ps
       Lots of other changes, see idoc.itx the user's manual.

    4) added support for MSDOS machines (this version and onwards will
       be developed on the PC---a 80386 machine).
    5) Corrected the ifm definitions for big i, dha-ya ligature, etc
       in the devnac.ifm file.
    6) -I ./xxx.ifm would not work, it would still search for the
       file xxx.ifm in the ITRANSPATH.
       Fixed so that now it realizes that ./xxx.ifm is a full path
       name and  does not look for in the ITRANSPATH.
    7) Changed variable name "inline" to "line_in", some compilers
       did not like the word "inline" (shades of C++...) [font.c]

--------------------------
****** Version 1.01, 11 June 1991

    Most of these bugs came about to support non-ansi systems..

    1)  stdlib.h is missing on many systems, so removed its
	inclusion from itrans.h (instead, added the declaration
	for getenv() - the only thing needed from stdlib.h).

    2)  sprintf() works differently on non-ansi-C machines - instead of
	returning number of characters printed, it simply returns a
	pointer to the string!
	So, changed itotex.c and itops.c to specifically use strlen()
	instead of relying on sprintf().
	Thanks to Dinesh Dattatraya Gaitonde (CMU) for catching this.

    3) Bug in function font.c::S_ccadd() - return TRUE; missing, added.

    4) Specifically define the macro YYDEBUG so as to include the
       integer yydebug in iyacc.c

    5) YFLAGS was missing from the Makefile, added it.
