GROFF_FONT_PATH
              A list of directories in which to seek the selected output
              device's directory of device and font description files.
              If, in the download file, the font file has been specified
              with a full path, no directories are searched.  See
              troff(1) and groff_font(5).

       GROPDF_NOSLIDE
              If this is set true, gropdf will ignore all commands which
              produce a presentation pdf, and produce a normal pdf
              instead.

       SOURCE_DATE_EPOCH
              A timestamp (expressed as seconds since the Unix epoch) to
              use as the creation timestamp in place of the current
              time.  The time is converted to human-readable form using
              Perl's localtime() function and recorded in a PDF comment.

       TZ     The time zone to use when converting the current time (or
              value of SOURCE_DATE_EPOCH) to human-readable form; see
              tzset(3).
