FreeType's header inclusion scheme
</h1></center>
<table align=center width="87%"><tr><td>
<p>To be as flexible as possible (and for historical reasons), FreeType uses a very special inclusion scheme to load header files, for example</p>
<pre class="colored">
  #include &lt;ft2build.h&gt;                                            
                                                                   
  #include FT_FREETYPE_H                                           
  #include FT_OUTLINE_H                                            
</pre>
<p>A compiler and its preprocessor only needs an include path to find the file &lsquo;ft2build.h&rsquo;; the exact locations and names of the other FreeType header files are hidden by preprocessor macro names, loaded by &lsquo;ft2build.h&rsquo;. The API documentation always gives the header macro name needed for a particular function.</p>
