Updated and expanded Lions V6 source v1.4
This is revision 1.4 of my updated and expanded edition of John Lions’ UNIX Operating System Source Code Level Six. It preserves Lions’ original source selection, organization, source-sheet numbering, and line references while reformatting the booklet for letter-size printing.
This edition also adds a table of contents, an alphabetical source-file listing, the locations of the files in a running V6 system, alphabetical procedure listings, file-and-procedure indexes, defined-symbol listings, source-code cross-references, and alphabetical and numerical symbol tables for the configured kernel.

Next, the reader will be led through adding a regular user, making the system multi-user capable. Then, the reader will be shown how to make the system multi-session cable allowing multiple simultaneous sessions. Finally, the system will be put to use with hello world, DMR style, and the learn system will be enabled.
