<h2 class="unnumbered">Option Index</h2>
<p><code>gfortran</code>&rsquo;s command line options are indexed here without any
initial &lsquo;<samp>-</samp>&rsquo; or &lsquo;<samp>--</samp>&rsquo;. Where an option has both positive and
negative forms (such as -foption and -fno-option), relevant entries in
the manual are indexed under the most appropriate form; it may sometimes
be useful to look up both forms.
