Emacs will configure itself to build with these libraries if the
`configure' script finds them on your system, unless you supply the
configure should avoid such old versions. If that happens, use the
--without-LIB options to `configure'. See below for more details.
+* Complex Text Layout support libraries
+
+Emacs needs the optional libraries "m17n-db", "libm17n-flt", "libotf"
+to correctly display such complex scripts as Indic and Khmer.
+On some systems, particularly GNU/Linux, these libraries may be
+already present or available as additional packages. Note that if
+there is a separate `dev' or `devel' package, for use at compilation
+time rather than run time, you will need that as well as the
+corresponding run time package; typically the dev package will contain
+header files and a library archive. Otherwise, you can download and
+build libraries from sources.
+
+The sources of these libraries are available by anonymous CVS from
+cvs.m17n.org.
+
+ % cvs -d :pserver:anonymous@cvs.m17n.org:/cvs/m17n login
+ % cvs -d :pserver:anonymous@cvs.m17n.org:/cvs/m17n co m17n-db
+ % cvs -d :pserver:anonymous@cvs.m17n.org:/cvs/m17n co m17n-lib
+ % cvs -d :pserver:anonymous@cvs.m17n.org:/cvs/m17n co libotf
+
+For m17n-lib, if you have problems with making the whole package
+because you lack some other packages on which m17n-lib depends, try to
+configure it with the option "--without-gui".
+
+Please note that Emacs must be configured with the arg
+"--enable-font-backend" to get the benefit of those libraries.

* Extra fonts
The Emacs distribution does not include fonts and does not install

newer is required for Emacs.

-`--with-gcc=no'. If you omit this option, `configure' will search

a POP3 server by default. Versions of the POP protocol older than
POP3 are not supported. For Kerberos-authenticated POP add

Use --without-xim to inhibit the default use of X Input Methods. In
