dvips: Including headers from the command line

 
 5.2.2 Including headers from the command line
 ---------------------------------------------
 
 You can include headers when you run Dvips, as well as from your
 document (see the previous section).  To do this, run Dvips with the
 option '-P HEADER'; this will read the file 'config.HEADER', which in
 turn can specify a header file to be downloaded with the 'h' option.
 ⇒Configuration file commands.  These files are called
 'HEADER.cfg' on MS-DOS.
 
    You can arrange for the same file to serve as a '-P' config file and
 the downloadable header file, by starting the lines of PostScript code
 with a space, leaving only the 'h' line and any comments starting in the
 first column.  As an example, see 'contrib/volker/config.*'
 ('contrib/volker/*.cfg' on MS-DOS). (These files also perform useful
 functions: controlling duplex/simplex mode on duplex printers, and
 setting various screen frequencies; 'contrib/volker/README' explains
 further.)
