about.

+   <para>
+   Patterns in apt are heavily inspired by patterns in aptitude, but with some tweaks:
+   </para>
+   <itemizedlist>
+      <listitem>
+         <para>Only long forms &mdash; the ones starting with ? &mdash; are supported</para>
+      </listitem>
+      <listitem>
+         <para>
+            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.
+         </para>

+      <listitem>
+         <para>Not all patterns are supported.</para>
