variable's @code{variable-documentation} property.

To save memory, the documentation for preloaded functions and
variables (including primitive functions and autoloaded functions) is
not kept in memory, but in the file
-@file{emacs/etc/DOC-@var{version}}, where @var{version} is the Emacs
-version number (@pxref{Version Info}).
+@file{emacs/etc/DOC}).

When a function or variable is loaded from a byte-compiled file during
@code{documentation} command, below).
If the value recorded in the property list refers to a documentation
-string stored in a @file{DOC-@var{version}} file or a byte-compiled
+string stored in a @file{DOC} file or a byte-compiled
file, it looks up that string and returns it. If the property value
isn't @code{nil}, isn't a string, and doesn't refer to text in a file,
then it is evaluated as a Lisp expression to obtain a string.
Emacs reads the file @var{filename} from the @file{emacs/etc} directory.
When the dumped Emacs is later executed, the same file will be looked
for in the directory @code{doc-directory}. Usually @var{filename} is
-@code{"DOC-@var{version}"}.

This variable holds the name of the directory which should contain the
-file @code{"DOC-@var{version}"} that contains documentation strings for
+file @code{"DOC"} that contains documentation strings for
built-in and preloaded functions and variables.
In most cases, this is the same as @code{data-directory}. They may be
