Plan 9 from Bell Labs 2nd Edition
Of special interest in this collection are:
- The “README” by Brian Kernighan - somewhat outdated, but still relevant today.
- The ALEF users guide by Bob Flandrena
- Alef Language Reference Manual by Phil Winterbottom
- A Quick Introduction to the Panel Library by Tom Duff - used by the Mothra web browser
- Raster Graphics in plan9 by Tom Duff - Ironically obsoleted the adoption in 3rd Edition of the Porter/Duff graphics model.
