What is Egal?

Egal is an open source mathematical proof checker which can be used to create Qeditas theories, signatures and documents.

Egal is released under the terms of the MIT license. See COPYING for more information or see http://opensource.org/licenses/MIT

Development History

The original version was developed by Chad E. Brown (mathgate.info) and released under an MIT license in 2014. In 2015 the Qeditas developers created this fork of Egal to support the creation of Qeditas theories, signatures and documents. The original version of Egal can still be found at https://mathgate.info/egal along with some documentation. Since there are some differences between the forks, the documentation available at mathgate.info is in some cases incompatible with this fork. However, if one adds the command line argument "-polyexpand" then the egal executable will for the most part behave like the original mathgate version. Most of the new code written to support Qeditas is in the src/qeditas directory.
