+<refsect2><title>Pinning by source package</title>
+<para>APT supports pinning by source packages. To pin by a source package,
+prepend "src:" to the package name.</para>
+<para>For example, to pin all binaries produced by the apt source package
+of this APT's version to 990, you can do:</para>
+<programlisting>
+Package: src:apt
+Pin: version &apt-product-version;
+Pin-Priority: 990
+</programlisting>
+
+<para>Source package pinning can be combined with regular expressions and
+glob patterns, and can also take a binary architecture.</para>
+<para>For example, let's pin all binaries for all architectures produced by
+any source package containing apt in its name to 990:</para>
+<programlisting>
+Package: src:*apt*:any
+Pin: version *
+Pin-Priority: 990
