When gstat is started, it first looks for an initialization file to
load. If the environment variable GSTATRC specifies a file name,
gstat will read the contents of this file, or else gstat will search for
the file $HOME/.gstatrc and read it when found. If present, the
initialization file should contain valid gstat commands. After reading
the initialization file, command line options are processed, and finally
the command file is processed. The processing order determines when
previously set commands will be overridden.
Information on gnuplot customization is obtained by starting gnuplot and typing ``help'' or ``help environment''. (If the help file is not found, the environment variable GNUHELP should be set to the gnuplot help file, gnuplot.gih.)
