The open source parts of ProofPower and all the documentation may be obtained from this site. The documentation covers the following packages:

The ProofPower packages are copyright © Lemma 1 Ltd. All the ProofPower packages except PPDaz are free, open-source, software made available under the terms of the GNU General Public License.

The PDF documentation for PPDaz is freely available to anyone who is interested and the PPDaz software is available under a free licence for non-profit use.

Downloading OpenProofPower

The recommended stable version of the open source distribution is working version 2.9.1w5. It is available here. Before downloading the distribution, you may like to read the description of the changes in this release and the read-me file. This version works with Poly/ML 5.3 and later and should be compatible with most C/C++ developer kits (including those that default to 32-bit architecture and those like Apple's Xcode tools that default to 64-bit architecture). Some earlier versions are available here. If you want to see what is coming in the next release, experimental versions are filed here from time to time.

System Requirements

OpenProofPower has been built and tested by Lemma 1 using: Poly/ML version 5.3 and 5.4; Standard ML of New Jersey (SML/NJ) version 110.54; x86 PC hardware, and Apple PowerPC and Intel hardware; Linux; OpenSolaris; Mac OS X with Apple's X11 distribution; Cygwin. For building and running ProofPower, Poly/ML is typically two to four times faster than SML/NJ and is the recommended compiler.

If you use SML/NJ, you must use version 110.54 or later. If you use Poly/ML, then you must use version 5.3 or later.

PPXpp requires OpenMotif 2.3 or later. As OpenMotif is not available on Cygwin, PPXpp is not currently supported on Cygwin.

If you are using Mac OS X, then there are some keyboard configuration files that you can download to make working with PPXpp (and other Motif applications) easier.
