Installation of Dvipage.
=======================

Dvipage previews DVI files on Sun workstations under SunView.
Version 3.0 has been tested on Sun 3 /160, /75, /60 under OS 3.5 and 4.0.1,
and also on a Sun 4/260 under OS 4.0.1.  An earlier version worked
on many other configurations also.

You should have the following files in a directory:

Installation is simple; however, there are some system dependent
parameters which must be set in the file dvipage.h, in particular,
the FONT_AREA definition must reflect the location of the TeX fonts
on your system;  in the file as provided, there are conditionals which
select a different font file location for different types of machine.
FONT_AREA is a colon separated list of directories where font files
will be found; either PXL or GF files can be used:

#ifndef FONT_AREA
#ifdef sparc
#define FONT_AREA \
  "/nfs/tex-server/tex/1988/lib/tex/fonts:/fonts/tex/pxl"
#else !sparc
#define FONT_AREA \
  "/nfs/tex-server/tex/1988/lib/tex/fonts:/usr/spar/font/tex/pxl"
#endif sparc
#endif  FONT_AREA

You should also alter PRINT_SPOOLER and PRINT_PAGE_SPOOLER also in
the file dvipage.h, in the obvious way to provide commands which can
be used to print either the whole document or a single page of the document.

/*
 * Define a command which will print the whole document.
 */
#ifndef PRINT_SPOOLER
#define PRINT_SPOOLER		"lpr -d %s >/dev/null 2>/dev/null"
#endif  PRINT_SPOOLER

/*
 * Define a command which will print the specified page of the document.
 */
#ifndef PRINT_PAGE_SPOOLER
#define PRINT_PAGE_SPOOLER \
	"texpagefilter -f %d -t %d %s | lpr -d >/dev/null 2>/dev/null"
#endif	PRINT_PAGE_SPOOLER

It may be that the simple PRINT_ definitions above do not have enough
flexibility to deal with the printer configurations at your site.
At Spar, we have some laserwriters and some imagen printers;
the following hacks in the file `dvipage.c' examine the PRINTER
environment variable and set the print_spooler and print_page_spooler
strings accordingly:

	/*
	 * Customise this part for your local printer environment.
	 * ======================================================
	 */
#ifdef SPAR_HACKS

	/*
	 * Set local printer hacks.
	 */
	printer = getenv("PRINTER");
	if(printer && strncmp(printer, "lw", 2) == 0)
	{
		sprintf(print_spooler,
		  "dvips -P%s %%s >/dev/null 2>/dev/null",
		  printer);
		sprintf(print_page_spooler,
		  "dvips -P%s -f %%d -t %%d %%s >/dev/null 2>/dev/null",
		  printer);
	}
	else if(printer && strncmp(printer, "im", 2) == 0)
	{
		sprintf(print_spooler,
		  "dviimp -P%s %%s >/dev/null 2>/dev/null",
		  printer);
		sprintf(print_page_spooler,
		  "dviimp -P%s -S %%d -E %%d %%s >/dev/null 2>/dev/null",
		  printer);
	}
	else
	{
		fprintf(stderr, "PRINTER environment not recognised:\n");
		fprintf(stderr, " using `%s' to print files\n",
		  print_spooler);
		fprintf(stderr, " using `%s' to print pages\n",
		  print_page_spooler);
	}

	if(verbose & DEBUG_PRINTER)
	{
		fprintf(stderr, "Using `%s' to print files\n",
		  print_spooler);
		fprintf(stderr, "Using `%s' to print pages\n",
		  print_page_spooler);
	}

#endif SPAR_HACKS

Remember to add a -DLOCAL_HACKS into the compile line in the Makefile,
or in dvipage.h, if you add something similar.

Finally, change the compile flags in `Makefile' if you are not
running on a Sun 3 with a f68881 floating point unit.

When all is set up, run `make'.  It will build a program called dvipage,
which can be installed in a suitable place.  The manual pages dvipage.1
should be installed in /usr/man/man1 as dvipage.1l, or in you local manual
pages directory.

Enjoy,
