Reading and Printing Lisp Objects
*********************************

   "Printing" and "reading" are the operations of converting Lisp
objects to textual form and vice versa.  They use the printed
representations and read syntax described in Note: Lisp Data Types.

   This chapter describes the Lisp functions for reading and printing.
It also describes "streams", which specify where to get the text (if
reading) or where to put it (if printing).

Streams Intro

Overview of streams, reading and printing.

Input Streams

Various data types that can be used as input streams.

Input Functions

Functions to read Lisp objects from text.

Output Streams

Various data types that can be used as output streams.

Output Functions
