#print
Each 'w' command typed so far has written the edited material
back on the same file that it came from originally.
This can be changed by giving a filename on the 'w' command:
  w camden
will write the current editor buffer
on file 'camden'.  What does the following
sequence of commands do?
   ex old
   w new
   q
As you can see, it picks up file 'old', and
writes it on file 'new'.  It has the same effect
as
   cp old new
does.

This directory contains a file
with a name beginning with 'h'.  Make a copy
of that file named 'norman'.  Check the copy
by listing the old and new files with 'cat' before
you type 'ready'.

Four score and seven years ago our
fathers brought forth on this continent
a new nation, conceived in liberty and
dedicated to the proposition that
all men are created equal.
