GRI_MERGE(1)						      General Commands Manual						      GRI_MERGE(1)

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 pre-
       sumed 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.
