##The Heirloom Project

This is a mirror of The Heirloom Project CVS repositories — a collection of hisorical UNIX tools, principally derived from System V, which have been patched to build on a modern system.

Particularly noteworthy are its historical Bourne shell, toolchain, and source code management tools — it includes some of the original implementations of m4, lex, yacc, SCCS, troff, etc.

Also included here are the related original vi and nail (mailx) repositories.

Changes relative to "https://github.com/eunuchs/heirloom-project":

• Reformat and add of fork change notes in this file.
• Added original heirloom-project files found to be missing as determined by a check out the original repository at "http://heirloom.cvs.sourceforge.net/". The files are apparently missing due to presence of files that cannot reside simultaneously on a case-insensitive file system:
