To install xyplot and related programs:

1.
   Edit the Makefile for the path dependencies in your case.  This means
   giving an appropriate value for PB and DBIN.  The variable PB tell where
   to install the PostScript prolog that is needed for printing and in
   general it is the directory where the xyplot source is.  The variable DBIN
   tells the Makefile where to install the executables.  In general it is
   the bin directory within your home directory.   Set the variable DIS to
   display if you want the XView previewer.

2.
   Type make and all the programs should compile.

3.
   Test the program by running xyplot on the sample files.  An easy way to
   do that in the csh is to type
	
	foreach file (*.xy)
	xyplot $file | display
	end

   After typing the foreach line the csh will prompt you with a ``?''; type
   in the other two lines.  After the end <carrige return> the first plot
   will be displayed on the screen and will remain there until any mouse
   button is pressed while the cursor is on the plot.

4.
   Test the printing program.  Type

	xyplot -s t4.xy | xyps | lpr

   This will produce a plot will all the plotting symbols available on the
   default printer (assumed to be a PostScript printer).

5.
   Install the programs by typing 

	make install

   If at any time you want to remove the programs type

	make deinstall

6.
   Print the xyplot manual by typing

	make xyman
	lpr xyman.ps

   or lpr -P PostScript if your default printer is not a PostScript
   printer.

7. 
   To install the manual pages copy xyplot.1 and xyps.1 into a manual
   directory.  If you are installing xyplot in your own directory, create a
   manual directory

	mkdir $HOME/man
	mkdir $HOME/man/man1

   and then copy the manual pages xyplot.1 and xyps.1 into $HOME/man/man1.
   After that set the enviornment variable MANPATH to the appropiate value.
   This is better done in your .login file by typing

	setenv MANPATH  :/usr/local/man:/usr/new/man:/usr/man:$HOME/man

   After this, the next time you login, you can type man xyplot xyps and get
   the manual page for xyplot and xyps.  To print the manual pages, type 
   man -t xyplot xyps

	make pages
