 <para>In <xref linkend="table.all-packages"/> we list all packages
 available in &ECL;. The nicknames are aliases for a package. Thus,
 <symbol>system:symbol</symbol> may be written as
 <symbol>sys:symbol</symbol> or <symbol>si:symbol</symbol>. The module field
 explains which library provides what package. For instance, the
 <package>ASDF</package> is obtained when loading the
 <package>ASDF</package> library with <code>(require 'asdf)</code>; and the
 <package>XLIB</package> package when configuring and loading the
 <package>CLX</package> library.</para>
