      <para>
       The tested string. This function is especially useful for filenames,
       but may also be used on regular strings.
      </para>
      <para>
       The average user may be used to shell patterns or at least in their
       simplest form to <literal>'?'</literal> and <literal>'*'</literal>
       wildcards so using <function>fnmatch</function> instead of
       <function>preg_match</function> for
       frontend search expression input may be way more convenient for
       non-programming users.
