3.3 Environment variables
=========================

Dvips looks for many environment variables, to define search paths and
other things.  The path variables are read as needed, after all
configuration files are read, so they override values in the
configuration files.  (Except for 'TEXCONFIG', which defines where the
configuration files themselves are found.)

   Note: (kpathsea)Path specifications, for details of interpretation
of path and other environment variables common to all Kpathsea-using
programs.  Only the environment variables specific to Dvips are
mentioned here.

'DVIPSDEBUG'
     Write the absolute path names of any configuration or map files to
     standard output, for debugging.  This isn't done by default because
     these files are read even before the banner is printed.  For
     voluminous additional debugging, set the environment variable
     'KPATHSEA_DEBUG' to '-1' (Note: (kpathsea)Debugging).  (If
     'KPATHSEA_DEBUG' is set to any value, it automatically turns on
     'DVIPSDEBUG'.)

'DVIPSFONTS'
     Default path to search for all fonts.  Overrides all the font path
     config file options and other environment variables (Note:
     (kpathsea)Supported file formats).

'DVIPSHEADERS'
     Default path to search for PostScript header files.  Overrides the
     'H' config file option (Note: Configuration file commands).

'DVIPSMAKEPK'
     Overrides 'mktexpk' as the name of the program to invoke to create
     missing PK fonts.  You can change the arguments passed to the
     'mktexpk' program with the 'MAKETEXPK' environment variable; Note:
     (kpathsea)MakeTeX script arguments.

'DVIPSRC'
     Specifies the name of the startup file (Note: Configuration file
     searching) which is read after 'config.ps' but before any
     printer-specific configuration files.

'DVIPSSIZES'
     Last-resort sizes for scaling of unfound fonts.  Overrides the 'R'
     definition in config files (Note: Configuration file commands).

'PRINTER'
     Determine the default printer configuration file.  (Dvips itself
     does not use 'PRINTER' to determine the output destination in any
     way.)

'TEXCONFIG'
     Path to search for Dvips' 'config.PRINTER' configuration files,
     including the base 'config.ps'.  Using this single environment
     variable, you can override everything else.  (The printer-specific
     configuration files are called 'PRINTER.cfg' on MS-DOS, but
     'config.ps' is called by that name on all platforms.)

'TEXPICTS'
     Path to search for included graphics files.  Overrides the 'S'
     config file option (Note: Configuration file commands).  If not
     set, 'TEXINPUTS' is looked for.  Note: (kpathsea)Supported file
     formats.
