Mit/Gnu Scheme

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. MIT/GNU Scheme is a free software Scheme implementation. MIT/GNU Scheme was free software even before the Free Software Foundation and GNU General Public License existed. It has a built-in Emacs-like editor called Edwin. The book Structure and Interpretation of Classical Mechanics has software which runs on MIT/GNU Scheme. Free software, software libre or libre software is software that can be used, studied, and modified without restriction, and which can be copied and redistributed in modified or unmodified form either without restriction, or with minimal restrictions only to ensure that further recipients can also do these things and that manufacturers of consumer-facing hardware allow user modifications to their hardware. Free software is generally available without charge, but can have a fee.
