+   <para>
+   Starting with version 2.0, <command>APT</command> provides support for

+   <title>Logic patterns</title>
+   <para>
+      These patterns provide the basic means to combine other patterns into

+      patterns.

+            Syntax is uniform: If there is an opening parenthesis after a term, it is always assumed to be the beginning of an argument list.
+         </para>
+         <para>
+            In aptitude, a syntactic form <code>"?foo(bar)"</code> could mean <code>"?and(?foo,bar)"</code> if foo does not take an argument. In APT, this will cause an error.
