The patch files in this directory correspond to the 9/1/92 release of
Obvius-2.2.  If you have an older version of Obvius, you must first
get a copy of this version of Obvius (get obvius-2.2.tar.Z).

There are a number of files in this directory called patch-n.lisp
(where n is a number).  These files should be placed in the
<obv>/patches subdirectory of the obvius source tree.  They will be
loaded automatically, in numerical order, starting from the current
value of the variable obvius::*starting-patch-file*.  We will
periodically post additional patches.  You should ftp these, and place
them in the <obv>/patches directory of your source tree.

If you save a new lisp executable (using obv::make-obvius), the
patches in the <obv>/patches directory will be preloaded and will
no longer need to be loaded at run time.  New patch files (added
after you've saved the executable) will still be loaded at run
time.

The modules directory contains patches for the various obvius optional
modules (e.g., svd.lisp, contour-plot.lisp) that are not loaded at
startup time.  These fixes cannot be put in patch-n.lisp files because
those patch files are loaded at startup time.  You should copy these
files into your <obv>/lisp-source directory.
