+# REDUCE
+
+## A portable general-purpose computer algebra system
+
+### Historical Snapshot Archive
+
+----
+
+## Introduction
+
+**REDUCE** is a freely available open-source interactive
+system for general algebraic computations, of interest to
+mathematicians, scientists, and engineers.
+
+It can be used interactively for simple calculations, but
+also provides a flexible and expressive user programming language.
+
+----
+
+## Historical Snapshots
+
+This repository contains informal (and not-guaranteed-complete)
+historical snapshots of some previous releases of Reduce.
+
+----
+
+## More Information
+
+*There should not be any binaries or serious build scripts here,
+and these are all to be viewed as* **OUT OF DATE** *and*
+**NOT SUPPORTED AT ALL.**
+
+However, some people may enjoy seeing how the code-base has grown,
+and getting a bit of insight into the world of the past. Developers
+tracking newly uncovered bugs may also find it useful to look back
+into these archives in case that provides insight.
+
+----
+
+## Support
+
+Please do not ask the **REDUCE** developers about building or
+installing from these old files. All current support is focused
+only on the main version.
+
+----
+
+## Licensing
+
+The files here typically have old restrictive copyright notices, and
+sometimes restrictive license terms. They are included here by virtue
+of the permission that their originators granted to Anthony C. Hearn
+and his distributors to use them.
+
+**You should not modify and redistribute** ***anything*** from this
+directory without _careful_ thought.
