	* These are all routines that handle operations on different
	types of geometric structures.  See the file "article.doc" in
	this directory for an overview of all the programs.  There is
	a manual page for each program that provides a more complete
	description.

	
HOW TO COMPILE THESE PROGRAMS


1. Unpack the directory tree.  Since you are reading this file, it is
assumed you've already done this.

2. Set the shell environment variable CPUTYPE to indicate what type of
machine you have.  It must be one of the following:
	sun3os3    - For the Sun 3, Operating System Version 3.x
	sun3os4    - For the Sun 3, Operating System Version 4.x
	sun4os4    - For the Sun 4 (SparcStation), Operating System
		     Version 4.x
	iris4      - For any Silicon Graphics Iris computer

For example, if you are using the C-Shell on a Sun 4, you would enter:
	% setenv CPUTYPE sun4os4
(The "%" is the shell prompt.)  If you are using the Bourne Shell on a
Sun 4, you would enter:
	$ CPUTYPE=sun4os4
	$ export CPUTYPE
(the "$" is the shell prompt.)

If you are not on a Sun or an Iris, pick the one you think it might be
closest to.

3. Look in the subdirectory Makefiles.  Edit the file mk.$CPUTYPE.
(Where $CPUTYPE is the value you assigned CPUTYPE in the previous
step.)  Make sure BIN_DIR, LIB_DIR, and MAN_DIR are set to the
directories you want to hold the binary, library, and manual page
files.

4. From the top directory in the tree (the one containing this file),
type "make recompile".  If all goes well, all the programs will be
compiled.

5. Type "make install" and all the programs will be installed in the
file system.  (You may need to be root or super-user for this step to
work.)
