+<p>The <em>-dddd</em> part is optional and can be used to apply more than one patch to
+an ebuild in the specified order. <em>d</em> should be a digit (0..9) and exactly
+4 digits are expected. The not-numbered patch is always applied first.
+So, in theory, up to 10001 patches per ebuild are supported.</p>
+<p>The <em>default</em> (version-agnostic) patches are only applied to ebuilds for
+which no version-specific patches exist.</p>
+<p>Exempting a specific ebuild from being patched can be achieved by creating
+an empty patch file (or a symlink to /dev/null). This is only necessary
