-To save space, the documentation for preloaded functions and variables
-(including primitive functions and autoloaded functions) is stored in
-the file @file{emacs/etc/DOC-@var{version}}---not inside Emacs. The
-documentation strings for functions and variables loaded during the
-Emacs session from byte-compiled files are stored in those files
-(@pxref{Docs and Compilation}).
-
-The data structure inside Emacs has an integer offset into the file, or
-a list containing a file name and an integer, in place of the
-documentation string. The functions @code{documentation} and
-@code{documentation-property} use that information to fetch the
-documentation string from the appropriate file; this is transparent to
-the user.

- The @file{emacs/lib-src} directory contains two utilities that you can
-use to print nice-looking hardcopy for the file
-@file{emacs/etc/DOC-@var{version}}. These are @file{sorted-doc} and
-@file{digest-doc}.
