SYNOPSIS

       What follows is an alphabetical list of all the NCAR Graphics environment variables and what they mean.

       NCARG_BIN,  if  set, indicates where the NCAR Graphics binaries are installed.  This environment variable
       takes precedence over NCARG_ROOT and doesn't need to be set unless  you  want  to  override  the  default
       ($NCARG_ROOT/bin).

       NCARG_CONFIG,  if  set,  indicates  where  the NCAR Graphics configuration files are installed (these are
       needed by site installers only).  This environment variable takes precedence over NCARG_ROOT and  doesn't
       need to be set unless you want to override the default ($NCARG_ROOT/lib/ncarg/config).

       variable  takes  precedence  over  NCARG_ROOT  and doesn't need to be set unless you want to override the
       default ($NCARG_ROOT/lib/ncarg/data).

       NCARG_ROOT,  indicates  the  parent directory where all of the NCAR Graphics binaries, libraries, include
       files, man pages, examples, etc. are installed.  This environment variable must be  set  by  anybody  who
       wants to run NCAR Graphics (or you can optionally set NCARG_LIB, NCARG_BIN, and NCARG_INCLUDE).

       NCARG_SYSRESFILE,  if  set,  indicates  where  the NCAR Graphics system resource file is installed.  This
       environment variable takes precedence over NCARG_ROOT and doesn't need to  be  set  unless  you  want  to
       override the default ($NCARG_ROOT/lib/ncarg/sysappres).

       NCARG_TESTS,  if  set,  indicates  where the NCAR Graphics test examples are installed.  This environment
       variable takes precedence over NCARG_ROOT and doesn't need to be set unless  you  want  to  override  the
