The Isabelle System Distribution
================================
Version information
-------------------
This is some repository version of Isabelle.
See the NEWS file in the distribution for details on user-relevant
changes.
Installation
------------
Isabelle works on the three main platform families: Linux, Windows,
and macOS.  The application bundles from the Isabelle web page
include sources, documentation, and add-on tools for all supported
platforms.
Some technical background information may be found in the Isabelle
System Manual (directory doc).
User interface
--------------
Isabelle/jEdit is an advanced Prover IDE based on jEdit and
Isabelle/Scala.  It is the main example application of the
Isabelle/PIDE framework, and the default user interface of
Isabelle.  It provides a metaphor of continuous proof checking of a
versioned collection of theory sources, with instantaneous feedback
in real-time and rich semantic markup associated with the formal
text.
