Is it just me or are the comments here missing the point?
This is the original writeup of Unix.  It&#x27;s amazingly well written and pretty complete for when it was done.  This is v0 of Unix, it&#x27;s barely started.<p>You could, and people did, write a lot of code with just that doc as documentation.<p>Maybe it&#x27;s because I&#x27;m a Bell Labs fanboy, I find this doc impressive.
