+/***en @section extralib External libraries and data
+
+The m17n library utilizes these external libraries. They are not
+mandatory but several functions of the m17n library depend on them.
+
+<ul>
+<li> m17n-db -- http://www.m17n.org/m17n-lib/download/m17n-db-1.2.0.tar.gz
+
+ Used by @ref m17nShell and @ref m17nGUI.
+
+<li> libxml2 -- http://xmlsoft.org/
+
+ Used by the functions mtext_serialize () and mtext_deserialize ().
+ Those functions return NULL when libxml2 is not available,
+
+<li> fribidi -- http://fribidi.sourceforge.net/
+
+ Used for BIDI processing. If it is not available, the rendering
+ engine of the m17n library can't handle such script as Arabic and
+ Hebrew correctly.
+
+<li> freetype -- http://www.freetype.org/
+
+ Used for handling local fonts.
+
+<li> fontconfig -- http://nexp.cs.pdx.edu/fontconfig/
+
+ Used for handling local fonts supported by the freetype library.
+
+<li> fontconfig -- http://freedesktop.org/Software/fontconfig
+
+ Used for finding local fonts in combination with Xft.
+
+<li> xft -- http://freedesktop.org/Software/Xft
+
+ Used for drawing text with local fonts by X Render Extension of X
+ server in combination with fontconfig.
+
+<li> GD
+
+ Used for rendering text with local fonts on bitmap/pixmap.
