A Few Buffer-Related Functions
******************************

   In this chapter we study in detail several of the functions used in
GNU Emacs.  This is called a "walk-through".  These functions are used
as examples of Lisp code, but are not imaginary examples; with the
exception of the first, simplified function definition, these functions
show the actual code used in GNU Emacs.  You can learn a great deal from
these definitions.  The functions described here are all related to
buffers.  Later, we will study other functions.
