+* Image support libraries
+
+Emacs needs optional libraries to be able to display images (with the
+exception of PBM and XBM images whose support is built-in).
+
+On some systems, particularly on GNU/Linux, these libraries may
+already be 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. None of them are vital for
+running Emacs; however, note that Emacs will not be able to use
+colored icons in the toolbar if XPM support is not compiled in.
+
+Here's the list of these optional libraries, and the URLs where they
+can be found:
+
+ . libXaw3d for fancy 3D-style
+ scroll bars: ftp://ftp.x.org/contrib/widgets/Xaw3d/
+ . libxpm for XPM: ftp://ftp.x.org/contrib/libraries/
+ Get version 3.4k or later, which lets Emacs
+ use its own color allocation functions.
+ . libpng for PNG: ftp://www.libpng.org/pub/png/
+ . libz (for PNG): http://www.info-zip.org/pub/infozip/zlib/
+ . libjpeg for JPEG: ftp://ftp.uu.net/graphics/jpeg/
+ Get version 6b -- 6a is reported to fail in
+ Emacs.
+ . libtiff for TIFF: http://www.libtiff.org/
+ . libungif for GIF:
+ http://prtr-13.ucsc.edu/~badger/software/libungif/index.shtml
+ Ensure you get version 4.1.0b1 or higher of libungif -- a bug in
+ 4.1.0 can crash Emacs.
+
+Emacs will configure itself to build with these libraries if the
+`configure' script finds them on your system, unless you supply the
+appropriate --without-LIB option. In some cases, older versions of
+these libraries won't work because some routines are missing, and
+configure should avoid such old versions. If that happens, use the
+--without-LIB options to `configure'. See below for more details.
+
+* Extra fonts
+
+At first, Emacs does not include fonts and does not install them. You
+must do this yourself.
+
+To take proper advantage of Emacs 21's mule-unicode charsets, you need
+a suitable font. For `Unicode' (ISO 10646) fonts for X, see
+<URL:http://dvdeug.dhis.org/unifont.html> (packaged in Debian),
+<URL:http://openlab.ring.gr.jp/efont/> (packaged in Debian). (In
+recent Debian versions, there is an extensive `misc-fixed' iso10646-1
+in the default X installation.) Perhaps also see
+<URL:http://www.cl.cam.ac.uk/%7Emgk25/ucs-fonts.html>.
+
+<URL:http://czyborra.com/charsets/> has basic fonts for Emacs's
+ISO-8859 charsets.
+
+XFree86 release 4 (from <URL:ftp://ftp.xfree86.org/> and mirrors)
+contains font support for most, if not all, of the charsets that Emacs
+currently supports, including iso10646-1 encoded fonts for use with
+the mule-unicode charsets. The font files should also be usable with
+older X releases. Note that XFree 4 contains many iso10646-1 fonts
+with minimal character repertoires, which can cause problems -- see
+etc/PROBLEMS.
+
+BDF fonts etl-unicode.tar.gz used by ps-print and ps-mule to print
+Unicode characters are available from <URL:ftp://ftp.x.org/contrib/fonts/>
+and <URL:ftp://ftp.xfree86.org/pub/X.Org/contrib/fonts/>.
+
+* GNU/Linux development packages
+
+Many GNU/Linux systems do not come with development packages by
+default; they just include the files that you need to run Emacs, but
+not those you need to compile it. For example, to compile Emacs with
+X11 support, you may need to install the special `X11 development'
+package. For example, in April 2003, the package names to install
+were `XFree86-devel' and `Xaw3d-devel' on RedHat. On Debian, the
+packages necessary to build the installed version should be
+sufficient; they can be installed using `apt-get build-dep emacs21' in
+Debian 3 and above.
