<p>
The <span class="emphasis"><em>UTF</em></span> presents you with 4 different variants how it
can be used.
</p>
<div class="orderedlist"><ol class="orderedlist" type="1">
<li class="listitem">
The static library variant
</li>
<li class="listitem">
The dynamic library variant
</li>
<li class="listitem">
The single-header variant
</li>
<li class="listitem">
The external test runner variant
</li>
</ol></div>
<p>
Unlike the Buridan's donkey though, you shouldn't have problems deciding
which one to use, since there are clear reasons why would you prefer each
one.
</p>
<p>
In most cases to compile a test module based on the <span class="emphasis"><em>UTF</em></span>
all you need to include is just the single header
</p>
<pre class="programlisting"><span class="preprocessor">#include</span> <span class="special">&lt;</span><span class="identifier">boost</span><span class="special">/</span><span class="identifier">test</span><span class="special">/</span><span class="identifier">unit_test</span><span class="special">.</span><span class="identifier">hpp</span><span class="special">&gt;</span>
</pre>
<p>
This header includes internally most of the other headers that contains the
<span class="emphasis"><em>UTF</em></span> definitions. Some advanced features, like the floating
point comparison or the logged expectations testing, are defined in independent
headers and need to be included explicitly.
