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

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

       (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).

       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

       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 default ($NCARG_ROOT/lib/ncarg/tests).

       NCARG_TMP, if set, indicates where NCAR Graphics temporary files should be written.
