      application.  If you just want to quickly try out neon, use
      the <a class="xref" href="refconfig.html" title="neon-config"><span class="refentrytitle">neon-config</span></a> script.</p><p>The neon source code is designed to be easily embedded
      into an application source tree.  neon has no dependencies on
      libraries other than an SSL toolkit and XML parser, though the
      source tree can be configured to have no support for SSL or XML
      if desired.  To configure the neon source code some <a class="ulink" href="http://www.gnu.org/software/autoconf/" target="_top">GNU autoconf</a>
      macros are supplied, which can be used in a number of ways, as
      follows:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>autoconf macros are distributed in the 'macros'
	  subdirectory of the neon distribution.  Use the NEON_LIBRARY
	  macro from your configure.in to check for the presence of
	  the neon library installed on the system.  The macro adds an
	  '--with-neon=...'  argument to configure, which allows the
	  user to specify a location for the library (the standard
	  /usr and /usr/local directories are checked automatically
	  without having to be specified).</p></li><li class="listitem"><p>The 'src' directory of the neon package can be
	  imported directly into your application, if you do not wish
	  to add an external dependency.  If you wish to bundle, use
	  the NEON_BUNDLED macro to configure neon in your application:
	  here, the neon sources are bundled in a directory called
	  'libneon':</p><pre class="programlisting">NEON_BUNDLED(libneon, ...)</pre><p>If your application supports builds where srcdir != builddir,
	  you should use the NEON_VPATH_BUNDLED macro like this:</p><pre class="programlisting">NEON_VPATH_BUNDLED(${srcdir}/libneon, libneon, ...)</pre><p>If you use this macro, a '--with-included-neon' option
	  will be added to the generated configure script.  This
	  allows the user to force the bundled neon to be used in the
	  application, rather than any neon library found on the
	  system. If you allow neon to be configured this way, you
	  must also configure an XML parser. Use the NEON_XML_PARSER
	  macro to do this.</p></li><li class="listitem"><p>The final argument to the _BUNDLED macros is a
	  set of actions which are executed if the bundled build *is*
	  chosen (rather than an external neon which might have been
	  found on the user's system).  In here, use either the
	  NEON_LIBTOOL_BUILD or NEON_NORMAL_BUILD macro to set up the
	  neon Makefile appropriately: including adding the neon source
	  directory to the recursive make.</p></li></ul></div><p>A full fragment might be:</p><pre class="programlisting">NEON_BUNDLED(libneon, [
  NEON_NORMAL_BUILD
  NEON_XML_PARSER
  SUBDIRS="libneon $SUBDIRS"
])</pre><p>This means the bundled neon source directory (called 'libneon')
	is used if no neon is found on the system, and the standard XML
	parser search is used.</p></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="features.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="intro.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="compliance.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Feature list </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> Standards compliance</td></tr></table></div></body></html>
