NAME

       gri_merge - merge multiple Gri output files into a single PostScript file.

USAGE (style 1):

              gri_merge [OPTIONS] CxR a.ps b.ps ... > merged_file.ps

       Merges  the  files onto one page, in 'C' columns and 'R' rows.  The CxR files are given in
       the order of words on a page.  The page is presumed to be 8.5x11in in size, as are all the
       input files, and the input files are sized to fit, and kept in natural scale.

USAGE (style 2):

              gri_merge [OPTIONS] xcm ycm enlarge a.ps [b.ps ...] > merged_file.ps

       Where  `enlarge'  is  a scale factor applied after offsetting `xcm' to the right and `ycm'
       upward.

   EXAMPLE (style 2):
              The following

       gri_merge 2 12 .5 a.ps \

              12 12 .5 b.ps \

              2 2 .5 c.ps \

              12 2 .5 d.ps > all.ps

       produces 4 panels from gri plots  done  using  margins  and  sizes  as  specified  in  the
       following lines in a gri commandfile

              set x margin 2

              set x size 15

              set y margin 2

              set y size 15

       The OPTIONS, available if your 'perl' has 'getopts' library, are:

       -u graylevel -- set graylevel for underlay beneath panels, by default 0.75.

              Values  range from 0 (black) to 1 (white), although a value of precisely 1 means do
              NOT draw underlay.

       -b graylevel -- Set value for background under individual panels, again 0

              for black to 1 for white, with 1 meaning no drawing.

       -h     -- Print this help message and quit.
