	    Proof General --- Organize your proofs! 

Proof General is a generic Emacs interface for proof assistants.
The aim of the Proof General project is to provide a powerful, generic
environment for using interactive proof assistants.

This is the ProofTreeBranch version of Proof General. It is the cvs 
development version of Proof General with special support for prooftree 
added, see http://askra.de/software/prooftree/.

A few example proofs are included in each prover subdirectory.  The
"root2" proofs of the irrationality of the square root of 2 were
proofs written for Freek Wiedijk's challenge in his comparison of
different theorem provers, see http://www.cs.kun.nl/~freek/comparison/.  
Those proof scripts are copyright by their named authors.  
(NB: most of these have rusted)
