Unix History Repository

The goal of this project is to create a git repository representing the Unix source code history, starting from the 1970s and ending in the modern time. To fulfill this goal the project brings data from early snapshots, repositories, and primary research. The project aims to put in the repository as much metadata as possible, allowing the automated analysis of Unix history.

Created by Diomidis Spinellis.

This is TexiWeb Jr., a super simple literate programming system built
on top of Texinfo and implemented in awk.

The "tangle" piece was successfully bootstrapped on November 4, 2013.
The "weave" piece started producing a reasonable-looking document
on November 11, 2013.

As of Fri Feb 19 12:07:09 IST 2016, both the source code and literate programming document
are licensed under the GNU GPL. See the file COPYING.

Other repositories from the same author are interesting too: e.g.
the portable C compiler

and a converter from RCS to git
