#  Bash file to convert the  .ps  output from  Intergraph  VERTICAL
#  ustation into a  .pdf  file.
#
#  Receive just one command line argument = the input  .ps  filename
#  Make up the output  .pdf  filename
#
#  First use sed to edit the input  .ps  file to:
#
#    - Change the  scale  from   0.240000 0.240000   to   0.250 0.255
#
#    - Increase the "pen width"  by one step  -  note the required order
#
#  Then use Ghostscript to make the  .ps  to  .pdf  conversion.
#
#    - For horozontal plots use  /Orientation 3
#    - For  vertical  plots use  /Orientation 0
