This is a patched version of dvi2ps-1.8j for System V Rel.4 machines.

This patch provides the following two feature.

 1. Performance improvement. SVR4's fseek function flushes the stream
    buffer unconditionally.  This causes a great performance problem when
    dvi2ps accesses font glyphs.  The patched version uses wrapper routines
    defined in xxstdio.c of the system's standard I/O to get rid of
    redundant buffer flushes.

 2. You can take a chance to generate missing fonts automatically by a
    program such as MakeTeXPK, which can be found in dvips package, by
    putting a new keyword "autoexec" and a new font type "auto" into the
    fontdesc file. On visiting a "font" line of "auto" type in the
    fontdesc, dvi2ps executes the program specified by the "autexec"
    keyword, in which "%R" and "%M" are substituted by the resolution of
    the current device and the required magnification in magstep,
    respectively.  The "autoexec" line must preceed the "font" lines
    of "auto" types in the fontdesc file.  This feature does not depend
    on SVR4, so can be enabled on any system.  You have to add
    -DUSE_AUTO_FONT to CFLAGS in Makefile to enable this.  The following
    is a fontdesc example which executes MakeTeXPK for missing fonts.

    #
    # Specify the program for automatic font generation, which is
    # supposed to put new PK fonts into /opt/tex/lib/fonts/pk/auto.
    autoexec	/opt/xdvi/bin/MakeTeXPK %f %m %R magstep\(%M\)
    #
    # First check the prepared PK fonts.
    font	pk * 3		/opt/tex/lib/fonts/pk/core/%f.%mpk
    #
    # Next check the PK fonts generated automatically before.
    font	pk * 3		/opt/tex/lib/fonts/pk/auto/%f.%mpk
    #
    # Try to generate the font by MakeTeXPK if its tfm file exists.
    font	auto * 0	/opt/tex/lib/fonts/tfm/%f.tfm
    #
    # Check the font generated automatically now.
    font	pk * 3		/opt/tex/lib/fonts/pk/auto/%f.%mpk
