 script</a> matching are based on a set of URLs defined by
 <dfn>match patterns</dfn>.  A match pattern is essentially a
 URL that begins with a permitted scheme (<code>http</code>,
 <code>https</code>, <code>file</code>, <code>ftp</code>, or
 <code>chrome-extension</code>),
 and that can contain '<code>*</code>' characters.
 The special pattern
 <code>&lt;all_urls&gt;</code> matches any URL
 that starts with a permitted scheme.
 Each match pattern has 3 parts:</p>
