  42 <h2 class='title'>Introduction</h2>
  43
  44 <p>The CUPS PPD API provides...</p>
  45
  46 <h2 class='title'>General Usage</h2>
  47
  48 <p>The <var>&lt;cups/ppd.h&gt;</var> header file must be included
  49 to use the <tt>ppd</tt> functions.</p>
  50
  51 <p>Programs using these functions must be linked to the CUPS
  52 library: <var>libcups.a</var>, <var>libcups.so.2</var>,
  53 <var>libcups.2.dylib</var>, <var>libcups_s.a</var>, or
  54 <var>libcups2.lib</var> depending on the platform. The following
  55 command compiles <var>myprogram.c</var> using GCC and the CUPS
  56 library:</p>
  57
  58 <pre class='command'>
  59 <kbd>gcc -o myprogram myprogram.c -lcups</kbd>
  60 </pre>
  61
  62 <h2 class='title'>Compatibility</h2>
  63
  64 <p>Unless otherwise specified, the PPD API functions require CUPS
  65 1.1 or higher.</p>
