groff: grohtml specific registers and strings

 
 7.8.2 'grohtml' specific registers and strings
 ----------------------------------------------
 
  -- Register: \n[ps4html]
  -- String: \*[www-image-template]
      The registers 'ps4html' and 'www-image-template' are defined by the
      'pre-grohtml' preprocessor.  'pre-grohtml' reads in the 'troff'
      input, marks up the inline equations and passes the result firstly
      to
 
           troff -Tps -rps4html=1 -dwww-image-template=TEMPLATE
 
      and secondly to
 
           troff -Thtml
 
      or
 
           troff -Txhtml
 
      The POSTSCRIPT device is used to create all the image files (for
      '-Thtml'; if '-Txhtml' is used, all equations are passed to 'geqn'
      to produce MathML, and the register 'ps4html' enables the macro
      sets to ignore floating keeps, footers, and headings.
 
      The register 'www-image-template' is set to the user specified
      template name or the default name.
