+          1.  Introduction
+
+
+               One  cool thing I like about the history of Unix is how
+
+          Unix developed into a document processing system.  The short
+
+          history of that is the Unix team wanted to  purchase  a  new
+
+          computer to keep working on Unix.  But management said "No."
+
+
+               Around that same time, the Patents team wanted to buy a
+
+          new  computer  to  write patent applications, but the vendor
+
+          hadn't finished the software yet.  The  Unix  team  went  to
+
+          them and said:
+
+
+              Hey,  if you buy us a new computer, we'll update the
+              existing roff typesetting system so  you  can  write
+              patent applications.
+
+
+
+               That's  how  Unix  created the first nroff program, new
+
+          roff.  Later, they updated nroff to become troff, the  type-
+
+          setter roff, and even later ditroff, the device idenependent
+
+          version of troff.
+
