This fork of eunuchs/heirloom-project adds some fixes for building on a modern Linux, although some components, notaby most of the devtools, are still broken. You probably want to export the $SHELL to avoid most of the edits I've made for my convenience, but you definitely want to compile heirloom-sh before attempting any of the devtools or pkgtools. See TODO for details.

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.
