### 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and these are all to be viewed as* **OUT OF DATE** *and*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.
----

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.
