The \$CAD_HOME value will be reflected in the \$CADDIR varible in the 
defs.mak files. It is only needed for installation so you can change
it by modifying the defs.mak after building.

You can create other custom configurations yourself.  Read the
maintainer's manuals for details.  In particular, you can have more than
one graphics driver installed.
 
We haven't been able to test all of these configurations.  If 
you develop modifications to Magic or to this configuration program,
please let us (magic-hackers@csl.cornell.edu) know.

Magic works with the following window configurations.  X11 is preferred.
	1) X11
	2) OpenGL
	3) SunView
	4) OS/2 Warp
	5) X10
	6) AED graphics terminal

Sometimes is it handy to eliminate modules from Magic, to make it smaller.
The following modules are optional:
    CALMA - module to read and write GDS-II format
    CIF - module to read and write CIF
    PLOT - plotting code
    READLINE - readline support on the command line
    NONMANHATTAN - support for non-manhattan geometry
    ROUTE - a whole bunch of routing tools
    SCM - a scheme command-line interpreter
    SIM - an interface to RSIM
    .magic - choice of new or old system startup (macro definition) file

You may need to update your system wide ".magic" file to eliminate use of these
modules.  (Look at "~cad/lib/magic/sys/.magic".)

Configuration completed.  The following files were changed:

        defs.mak (old version in old.defs.mak)

Now you need to look at defs.mak and make sure it makes sense. 

Then type "make".

After it completes, you'll have a magic binary in the magic
sub directory and a graphics helper program in the graphics subdir.

Now type "make install".

This will install the appropriate files in ``$CADDIR''.

Log files of the make process are found in make.log and install.log.

To run magic, needs to find the X*Helper program in your path. It also
needs to find the tech libraries. The easiest way to do this is to:

        setenv CAD_HOME $CADDIR
        set path = ( \$path $CADDIR/bin )

If you have any problems, please read a man page or two and try
to figure it out. If you're stuck, send us (magic-hackers@csl.cornell.edu)
mail and we'll try to help.
