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.
