The X bdf Tamil font that I have derived has the following characterstics:

(a) I am using ADOBE courier font for character codes 0-127.
    ADOBE and DEC owns the copyright for this font.

(b) I am using U. of Washington's Thomas Ridgeway's Tamil font for character
    codes 128-255. Thomas Ridgeway owns the copyright for
    this Tamil font.

Having both ASCII and Tamil in the same font has the following
advantages:
  (1) All the existing X applications can be used
      without any modifications with Tamil fonts.
  (2) Because of (1), all one need to convert an X application to
      a Tamil application is to link my Tamil library
      before Athena X widget library when creating the executable.
      Lo and behold, you get Tamil X application without
      any extra work.

Otherwise, one have to extensively modify or completely rewrite
the X application to accept Tamil fonts. Such is the case for
all designs that uses two or more fonts like Japanese, Chinese,
Thai, etc. We avoid such needless expensive work by using both
ASCII and Tamil in the same font and a Tamil library which takes
care of keyboard input of Tamil characters.

WN Tamil METAFONT fonts were developed by Thomas Ridgeway
of University of Washington. Without his WN Tamil fonts, this project
wouldn't even have been conceived. We are all indebted to
him.

X TAMIL FONTS INSTALATION 
-------------------------
In order to setup the font to be accessed by X applications,
do the following:
	(a) xmkmf
	(b) make fontdir install
	(c) xset fp+ FONTINSTDIR
	    grep FONTINSTDIR Makefile to get the value of FONTINSTDIR
	(d) if step (c) gives the following error,
  		X Error of failed request:  BadValue (integer parameter
						out of range for operation)
  		Major opcode of failed request:  51 (X_SetFontPath)
  		Value in failed request:  0x5
  		Serial number of failed request:  4
  		Current serial number in output stream:  6
            you need to choose a FONTINSTDIR that can be accessed
	    by your X server. Contact your systems administrator
	    or your local unix/X guru if you need help.
	(e) xset q
	     check if FONTINSTDIR is added to your font path.
	(f) xfd -fn tamil-10
	     to see how the Tamil font looks like.

If you are using XNEWS (only sun openwindow users), then use the
following to install the fonts
	(a) imake -DUseInstalled -I/X11.5/lib/X11/config -DOPENWIN
	    where use appropriate path name for /X11.5/lib/X11/config
	(b) make FONTDIR=/home/user
	    That will install the fonts in the directory /home/user/tamil.
	    Use appropriate path for FONTDIR.
	(c) Use the fonts as you would in openwindows.
