2> <A name=using>Accessing the Flag</A> </h2>

<p>All defined flags are available to the program as just a normal
variable, with the prefix <code>FLAGS_</code> prepended.  In the above
example, the macros define two variables, <code>FLAGS_big_menu</code>
(a bool), and <code>FLAGS_languages</code> (a C++ string).</p>

<p>You can read and write to the flag just like any other
variable:</p>
<pre>
   if (FLAGS_consider_made_up_languages)
     FLAGS_languages += ",klingon";   // implied by --consider_made_up_lan
