The "geomutil" package contains a collection of geometric utilities
for use with geomview, the Geometry Center's 3D viewing tool.  The
utilities are provided in both C-library and shell-command versions.
The C-library versions are in src/lib/geomutil; the shell-command
versions are in src/bin/geomutil.

The utilities include:

	anytooff:	convert any geom to an OFF file
	offcombine:	combine two OFF files into one
	offconsol:	consolidate duplicate vertices in an OFF file
	bdy:		compute the boundary (edge) of a geom

To install:

0. You must have the geomview source tree on-line; let $GEOM stand for
   the root of this tree (the directory containing the "makefiles" and
   "src" subdirectories, among others).

1. Unpack the geomutil archive file into the $GEOM directory:

	% cd $GEOM ; uncompress < geomutil.tar.Z | tar xvopf -

   It is important that you unpack directly into the $GEOM directory
   (i.e. give the "tar" command with $GEOM as the current directory)
   because the archive assumes a certain directory structure.

   The archive unpacks the files README.geomutil (this file),
   Makefile.geomutil, and the directories src/bin/geomutil and
   src/lib/geomutil.

   Presumably, since you are reading this file, you have already
   done this step.

2. Configure your shell to do geomview-like compilations; do this
   by sourcing the "config" script in the GEOM directory:

	% cd $GEOM ; source config

   This sets various environment variables, most importantly the
   MACHTYPE variable for determining the type of machine you're on
   ("sgi", or "next" or ???).

3. Install the geomutil header files:

	% make -f Makefile.geomutil installh

   NOTE:  You must do this before compiling geomutil.

4. Compile the package:

	% make -f Makefile.geomutil

5. Install the package:

	% make -f Makefile.geomutil install

   This installs the library file libgeomutil.a in
   $GEOM/lib/${MACHTYPE}, various header files in $GEOM/include,
   various executable programs in $GEOM/bin/${MACHTYPE}, and man pages
   in $GEOM/man/man1, $GEOM/man/man3 (nroff source) $GEOM/man/cat1,
   and $GEOM/man/cat3 (formatted copies).

   If you want to install these in other directories outside the
   geomview source tree you may now copy them to their installed
   locations.
