INSTALLATION INSTRUCTIONS

To install, do the following:
    1.	Read the ENVIRONMENTS section of xdvi.man.sed to determine the correct
	default values for the XDVIFONTS and XDVISIZES environment variables.
	Edit the Imakefile or Makefile and change the values of the make
	variables DEFAULT_FONT_PATH and DEFAULT_FONT_SIZES to these values.

	(Note:  for X10 compilation, use Makefile_10 instead of Makefile.)

	You may also wish to change other compilation options; they are
	described later in this file.

    2.  make xdvi and try it out.  If the settings in step one are incorrect,
	you can use the corresponding environment variables to quickly try out
	different values.  If the values set in step 1 were incorrect,
	rm pxl_open.o and go back to step 1.

    3.  make xdvi.man.

    4.  Install xdvi and xdvi.man.


	The X10 flag only affects xdvi.c and pxl.c (and the flags MSBITFIRST,
	BMSHORT, and BMLONG, see below).

	You can also change the `make' variables FONTFORMATS_C and FONTFORMATS_O
	to reflect which font formats are actually used at your site.

Other compilation flags are:
	FONT_PATH	(xdvi.c)  Name of the environment variable to use when
			searching for the font path
	DEFAULT_FONT_PATH  (xdvi.c)  Name of the default font path to use when
			the above environment variable is not set.  See the
			ENVIRONMENT section of the man page for details on
			how to get xdvi to recognize the directory structure
			you use for storing fonts.
	SYSV		(dvi_init pxl_open xdvi.c)  Set for System V
			compilation.
	VMS		Set for VMS compilation.
	MSBITFIRST	(X11 only; xdvi.c dvi_draw.c gf.c pk.c pxl.c)  Store
			bitmaps internally with the most significant bit at
			the left.  For performance reasons, it would be best
			to set this to coincide with what your server uses.
			Use the keystroke '^P' to find information in this
			regard.  Generally, you should use MSBITFIRST if and
			only if '^P' reports bitord = 1, and BMSHORT/BMLONG
			(below) should be set to match whatever '^P' reports
			under "Unit =".  But, if bitord = byteord, then the
			latter setting should not matter much.
	BMSHORT		(X11 only; xdvi.c dvi_draw.c gf.c pk.c pxl.c)  Store
			bitmaps in short integers instead of bytes.  See
			MSBITFIRST for other relevant comments.  To check
			performance, you can use:
				time xdvi -d 8 file.dvi
	BMLONG		(X11 only; xdvi.c dvi_draw.c gf.c pk.c pxl.c)  Store
			bitmaps in long integers instead of bytes.
	ALTFONT		(xdvi.c)  Default font to use if the font named in the
			dvi file cannot be found.  Can be set to NULL.  By
			default, it is "cmr10".
	NOTOOL		(X11 only; xdvi.c)  Compile using raw X calls.
	BUTTONS		(xdvi.c)  Put radio buttons on the right side of the
			window for commonly used commands.
	A4		(xdvi.c)  Use European size paper by default.

All flags should be set in the appropriate Makefile via the variable
``DEFINES''.

================================================================

Notes of historical nature follow.  Most recent changes are listed at the end
of the file.

================================================================

This directory contains a version of xdvi capable of reading GF, PXL
and PK font files. This version of xdvi is based on the source that
"came with" X v10r3. Xdvi was modified by Paal Kvamme at the Norwegian
Institute of Technology, based on the modifications I had made to
dviimp (a dvi to ImPress converter). This code was again more or less
directly translated from the web source of PKtoPX.

If you discover (and fix) any bugs in this code, please notify me, so
I can make the corresponding changes myself.

================================================================
Also has path search added by Mark Eichin, looks in TEXFONTS
================================================================

================================================================
Additional notes:
	X11 version now works on the IBM PC/RT as well as VAX.
			[eichin:19880313.1330EST]
================================================================
*MORE* fixes (for athena release locker) [eichin:19880722.2058EST]
Fixes:
	narrow vertical and horizontal lines no longer disappear.
	bogus underlining (which usually occured on even sample sizes
of odd sized characters) no longer occurs.
	-S number (or typing number followed by S) will adjust the
sampling fraction; 0 is special cased to mean if anything in the
sampled zone is set, set the sample, else clear it. Interesting to
experiment with, though not useful for reading (the default value of 3
is just right.)
	-display and -geometry arguments work (so do old style forms,
though they were broken before)
	fixed one of the PK debugging messages to print the correct
font name instead of printing the pointer as text.
	included Ken Raeburn <raeburn>'s changes to support multiple
screens.
================================================================
More changes:

    1.  Incorporated the bitmap under a viewport widget using the toolkit
	(X11 only);
    2.  Added an icon and icon geometry arguments (X11 only);
    3.  Supported window resizing;
    4.  Added a 'c' option to move whatever is currently under the cursor to
	the center of the window;
    5.  Added an 'R' option to reread the .dvi file, and added logic to make
	'R' happen automatically whenever any part of the window is exposed
	and the dvi file changes (so that you can iconify xdvi, run tex,
	deiconify xdvi, and voila!);
    6.  Added a 'magnifying glass':  when you push a button, a window pops
	up, showing the region of the page, unshrunk;
    7.  Added support for gf fonts;
    8.  Upgraded font searching (at our site we use /usr/custom/tex82/gf
	for gf fonts, /usr/custom/tex82/pk for pk fonts, etc.);
    9.  Made numerous internal changes (removed all the lint I could,
	made unshrunk bitmaps permanently resident, which speeds up size
	changing, made table.h necessary only for pxl.h, split up the source
	file into xdvi.c, dvi.c, gf.c, pxl.c, and pk.c, made shrinking occur
	relative to the character's hot point, etc.)
   10.  The program reads SIGIO signals and processes incoming events
	immediately, so that it can stop displaying things that would be
	erased anyway.  If these interrupts are not coming through, then
	it also checks for incoming events every several dozen characters
	displayed.
   11.  Further split up dvi.c into dvi_init.c and dvi_draw.c; added
	compilation options for various internal bitmap representations.
	Fixed it so gcc won't give warnings, and so it works with R3 toolkit.
--  Patchlevel 2:  --
   12.  Added MAXCHARS compilation option.  Eliminated the nonsense with
	generating table.h.
--  Patchlevel 3:  --
   13.  Added -altfont command line option and SYSV compilation option.
================================================================================

4/1989  Modified for System V boxes. -DSYSV compiler option.

Donald Richardson, donr@crystal.mie.clarkson.edu

================================================================================
--  Patchlevel 4:  --
   14.  Removed MAXCHARS compilation option.  It's automatic now.  Made X10
	scrolling smoother.  Implemented the moving magnifying glass.
--  Patchlevel 5:  --
   15.  Implemented compilation without the toolkit, as well as scrollbars
	and tpic support in X10.  Also this version should work with color
	VAXstations, although overstrike characters will come out incorrectly.
   16.  Fixed a bug in gf reading routines:  specials at the beginning of
	a character def. were not being processed.  Thanks to
	kevin@amath.washington.edu for a bug report and fix.
   17.  Added 'k' keystroke.
--  Patchlevel 6:  --
   18.  Added buttons on the right side of the window.
   19.  Added -pagewidth and -pageheight command line options and A4
	compilation option.
   20.  Added a yet more robust font finding algorithm.
--  Patchlevel 7:  --
   21.  Replaced -pagewidth and -pageheight options with -paper.
--  Patchlevel 8:  --
   22.  Added compatibility for X11R4 and VMS.  Fixed up alignment of rules.
--  Patchlevel 9:  --
   23.	Removed obsolete '#' and '=' options from the X11 version:  they
	interfere with emacs.
