This directory contains a copy of John Lion's “A commentary on the Sixth Edition UNIX Operating System”. This form of the document is the one that Warren Toomey published on the USENET alt.folklore.computers newsgroup in May 1994. It's available in several forms:

• A gzipped tarball of the files after I had unpacked them and formatted them to PostScript in June 1994. This tarball includes separate PostScript files for the odd and even pages, for printing out in a double-sided format. It also contains a PDF file generated in April 2004. It is 1.75 MB in size.

• The book in gzipped PostScript, for printing out directly. It's 300 kB in size.

• The book in PDF, for printing out or displaying directly. It's 625 kB in size.

• The source form of the book, with a Makefile and targets to build PostScript and PDF versions. This is by far the smallest, only 170 kB.

• The complete source tree is available for perusal.

• The scans include a number of scan errors. Brian Foley was kind enough to supply errata that still need to be incorporated into the document.

The source code is not included, but you can get that from cuzco.com, also courtesy of Warren Toomey.
