Added the following lemmas tp Divides and a few others to Arith and NatDef:
div_le_mono, div_le_mono2, div_le_dividend, div_less_dividend
Fixed a broken proof in WF_Rel.ML. No idea what caused this.

IMPORTANT NOTE: This file describes the *new* installation procedure
using various scripts that are still supposed beta for Isabelle94-8.
If you encounter serious problems, you may want to consider compiling
Isabelle the olden way, as described in README.old.

Isabelle installation notes
===========================
Unpacking the archive
---------------------
After unpacking the Isabelle distribution archive (using tar and gzip)
you are left with some directory IsabelleYY-X. You may install this
anywhere, but please just *not* as ~/isabelle!!!
The place where you put the contents of IsabelleYY-X will be referred
to as [ISABELLE_HOME] subsequently.
Auto configuration
------------------
There are some minor adaptions to be made of the Isabelle distribution
to your system environment. Simply type:
cd [ISABELLE_HOME]
./configure
ML system settings and compilation
----------------------------------
Before actual compilation you have to tell Isabelle about your
Standard ML system. These settings reside in ./etc/settings, which
may be also overridden by ~/isabelle/etc/settings. There are already
various sample configurations in ./etc/settings commented out.
To build the core Isabelle/Pure and the default object-logic, just
type:
./build
More object-logics can be made similarly:
./build FOL HOL
Running the system
------------------
Provided that compilation was successful, you can now run something
like:
[ISABELLE_HOME]/bin/isabelle FOL
This starts an interactive Isabelle session within your current text
terminal. You may want to put [ISABELLE_HOME]/bin into your shell's
search PATH. Please do *not* copy (or link) the Isabelle scripts
somewhere else -- or they just won't work!
