The Definition of `insert-buffer'
=================================

   `insert-buffer' is yet another buffer-related function.  This
command copies another buffer _into_ the current buffer.  It is the
reverse of `append-to-buffer' or `copy-to-buffer', since they copy a
region of text _from_ the current buffer to another buffer.

   In addition, this code illustrates the use of `interactive' with a
buffer that might be "read-only" and the important distinction between
the name of an object and the object actually referred to.
