The Third Research Edition Unix Programmer's Manual
This repository maintains the tools for formatting and making available the Unix Programmer's Manual (Third Edition, February 1973). The generated formatted manual is made available in PDF form.
The manual pages and tools are derived from 1973 material unearthed by Dennis Ritchie, and made available through the The Unix Heritage Society. This is the last edition of the manual that was created in nroff (line-printed) form (rather than typeset with troff). I corrected some minor markup glitches through commits that are recorded in this repository. You can find the evolution of the manual pages recorded in the Unix history repository. Furthermore, you can find the evolution of the corresponding facilities on a series of tables available here.
