* leim-M.N.tar.gz
The Emacs Lisp code for input methods for various international
-character scripts is distributed in a separate tar file because of its
-large size. This file is called leim-M.N.tar.gz, with the same
-version number as Emacs, and it unpacks into the directory
-emacs-M.N/leim. Thus, if you unpack it in the same directory where
-you unpacked the Emacs distribution, it fills in a subdirectory
-of the Emacs distribution.
-
-If you have already unpacked the Leim tar file into a subdirectory of
-the Emacs sources, building and installing Emacs automatically
-installs the input method support as well. If you unpack the Leim tar
-file into the Emacs sources after building and installing Emacs, just
-build Emacs again and install it again.
+character scripts is distributed in a separate tar file because it
+amounts to a significant fraction of the size of the distribution.
+This tar file is called leim-M.N.tar.gz, with the same version number
+as Emacs, and it unpacks into the directory emacs-M.N/leim.
+
+You should unpack leim-M.N.tar.gz into the same directory where you
+have previously unpacked the main Emacs distribution. It fills in the
+contents of one subdirectory, which is present in the main Emacs
+distribution only in dummy form.
+
+Once you have unpacked the Leim tar file into the Emacs source tree,
+building and installing Emacs automatically installs the input method
+support as well. If you have built Emacs without unpacking Leim
+first, just unpack Leim, build Emacs again, and install it again.

Using @code{eval-when-compile} avoids loading @var{bar} when
the compiled version of @var{foo} is @emph{used}.
+@item
+Please don't require the @code{cl} package of Common Lisp extensions at
+run time. Use of this package is optional, and it is not part of the
+standard Emacs namespace. If your package loads @code{cl} at run time,
+that could cause name clashes for users who don't use that package.
+
+However, there is no problem with using the @code{cl} package at compile
+time, for the sake of macros. You do that like this:
+
+@example
+(eval-when-compile (require 'cl))
+@end example
