<P>This programmers manual describes Mini-XML version 2.7, a small XML
 parsing library that you can use to read and write XML data files in
 your C and C++ applications.</P>
<P>Mini-XML was initially developed for the <A href="http://gutenprint.sf.net/">
Gutenprint</A> project to replace the rather large and unwieldy <TT>
libxml2</TT> library with something substantially smaller and
 easier-to-use. It all began one morning in June of 2003 when Robert
 posted the following sentence to the developer's list:</P>
<BLOCKQUOTE><EM>It's bad enough that we require libxml2, but rolling our
 own XML parser is a bit more than we can handle.</EM></BLOCKQUOTE>
<P>I then replied with:</P>
<BLOCKQUOTE><EM>Given the limited scope of what you use in XML, it
 should be trivial to code a mini-XML API in a few hundred lines of
 code.</EM></BLOCKQUOTE>
<P>I took my own challenge and coded furiously for two days to produced
 the initial public release of Mini-XML, total lines of code: 696.
 Robert promptly integrated Mini-XML into Gutenprint and removed
 libxml2.</P>
<P>Thanks to lots of feedback and support from various developers,
 Mini-XML has evolved since then to provide a more complete XML
 implementation and now stands at a whopping 3,965 lines of code,
 compared to 103,893 lines of code for libxml2 version 2.6.9.</P>
<P>Aside from Gutenprint, Mini-XML is used for the following
 projects/software applications:</P>
<UL>
<LI><A href="http://www.cups.org/">CUPS</A></LI>
<LI><A href="http://zynaddsubfx.sourceforge.net">ZynAddSubFX</A></LI>
</UL>
<P>Please email me (mxml @ easysw . com) if you would like your project
 added or removed from this list, or if you have any comments/quotes you
 would like me to publish about your experiences with Mini-XML.</P>

hspace="10" src="1.gif" width="100"></A>Building, Installing, and
 Packaging Mini-XML</H1>
<P>This chapter describes how to build, install, and package Mini-XML on
 your system from the source archive. You will need an ANSI/ISO-C
 compatible compiler to build Mini-XML - GCC works, as do most vendors'
 C compilers. If you are building Mini-XML on Windows, we recommend
 using the Visual C++ environment with the supplied solution file. For
 other operating systems, you'll need a POSIX-compatible shell and <TT>
make</TT> program in addition to the C compiler.</P>
<H2><A NAME="2_1">Compiling Mini-XML</A></H2>
<P>Mini-XML comes with both an autoconf-based configure script and a
 Visual C++ solution that can be used to compile the library and
 associated tools.</P>
<H3><A NAME="2_1_1">Compiling with Visual C++</A></H3>
<P>Open the<VAR> mxml.sln</VAR> solution in the<VAR> vcnet</VAR> folder.
 Choose the desired build configuration, &quot;Debug&quot; (the default) or
 &quot;Release&quot;, and then choose<VAR> Build Solution</VAR> from the<VAR>
 Build</VAR> menu.</P>
<H3><A NAME="2_1_2">Compiling with Command-Line Tools</A></H3>
<P>Type the following command to configure the Mini-XML source code for
 your system:</P>
<PRE>
    <KBD>./configure ENTER</KBD>
</PRE>
<P>The default install prefix is<VAR> /usr/local</VAR>, which can be
 overridden using the <KBD>--prefix</KBD> option:</P>
<PRE>
    <KBD>./configure --prefix=/foo ENTER</KBD>
</PRE>
<P>Other configure options can be found using the <KBD>--help</KBD>
 option:</P>
<PRE>
    <KBD>./configure --help ENTER</KBD>
</PRE>
<P>Once you have configured the software, use the <TT>make(1)</TT>
 program to do the build and run the test program to verify that things
 are working, as follows:</P>
<PRE>
    <KBD>make ENTER</KBD>
</PRE>
<H2><A NAME="2_2">Installing Mini-XML</A></H2>
<P>If you are using Visual C++, copy the<VAR> mxml.lib</VAR> and and<VAR>
 mxml.h</VAR> files to the Visual C++<VAR> lib</VAR> and<VAR> include<VAR>
 directories, respectively.</VAR></VAR></P>
<P>Otherwise, use the <TT>make</TT> command with the <KBD>install</KBD>
 target to install Mini-XML in the configured directories:</P>
<PRE>
    <KBD>make install ENTER</KBD>
</PRE>
<H2><A NAME="2_3">Creating Mini-XML Packages</A></H2>
<P>Mini-XML includes two files that can be used to create binary
 packages. The first file is<VAR> mxml.spec</VAR> which is used by the <TT>
rpmbuild(8)</TT> software to create Red Hat Package Manager (&quot;RPM&quot;)
 packages which are commonly used on Linux. Since <TT>rpmbuild</TT>
 wants to compile the software on its own, you can provide it with the
 Mini-XML tar file to build the package:</P>
<PRE>
    <KBD>rpmbuild -ta mxml-<I>version</I>.tar.gz ENTER</KBD>
</PRE>
<P>The second file is<VAR> mxml.list</VAR> which is used by the <TT>
epm(1)</TT> program to create software packages in a variety of formats.
 The <TT>epm</TT> program is available from the following URL:</P>
<PRE>
    <A href="http://www.epmhome.org/">http://www.epmhome.org/</A>
</PRE>
<P>Use the <TT>make</TT> command with the <KBD>epm</KBD> target to
 create portable and native packages for your system:</P>
<PRE>
    <KBD>make epm ENTER</KBD>
</PRE>
<P>The packages are stored in a subdirectory named<VAR> dist</VAR> for
 your convenience. The portable packages utilize scripts and tar files
 to install the software on the target system. After extracting the
 package archive, use the<VAR> mxml.install</VAR> script to install the
 software.</P>
<P>The native packages will be in the local OS's native format: RPM for
 Red Hat Linux, DPKG for Debian Linux, PKG for Solaris, and so forth.
 Use the corresponding commands to install the native packages.</P>

<H1 align="right"><A name="BASICS"><IMG align="right" alt="2" height="100"
hspace="10" src="2.gif" width="100"></A>Getting Started with Mini-XML</H1>
<P>This chapter describes how to write programs that use Mini-XML to
 access data in an XML file. Mini-XML provides the following
 functionality:</P>
<UL>
<LI>Functions for creating and managing XML documents in memory.</LI>
<LI>Reading of UTF-8 and UTF-16 encoded XML files and strings.</LI>
<LI>Writing of UTF-8 encoded XML files and strings.</LI>
<LI>Support for arbitrary element names, attributes, and attribute
 values with no preset limits, just available memory.</LI>
<LI>Support for integer, real, opaque (&quot;CDATA&quot;), and text data types in
 &quot;leaf&quot; nodes.</LI>
<LI>&quot;Find&quot;, &quot;index&quot;, and &quot;walk&quot; functions for easily accessing data in
 an XML document.</LI>
</UL>
<P>Mini-XML doesn't do validation or other types of processing on the
 data based upon schema files or other sources of definition
 information, nor does it support character entities other than those
 required by the XML specification.</P>
<H2><A NAME="3_1">The Basics</A></H2>
<P>Mini-XML provides a single header file which you include:</P>
<PRE>
    #include &lt;mxml.h&gt;
</PRE>
<P>The Mini-XML library is included with your program using the <KBD>
-lmxml</KBD> option:</P>
<PRE>
    <KBD>gcc -o myprogram myprogram.c -lmxml ENTER</KBD>
</PRE>
<P>If you have the <TT>pkg-config(1)</TT> software installed, you can
 use it to determine the proper compiler and linker options for your
 installation:</P>
<PRE>
    <KBD>pkg-config --cflags mxml ENTER</KBD>
    <KBD>pkg-config --libs mxml ENTER</KBD>
</PRE>
<H2><A NAME="3_2">Nodes</A></H2>
<P>Every piece of information in an XML file is stored in memory in
 &quot;nodes&quot;. Nodes are defined by the <A href="#mxml_node_t"><TT>
mxml_node_t</TT></A> structure. Each node has a typed value, optional
 user data, a parent node, sibling nodes (previous and next), and
 potentially child nodes.</P>
<P>For example, if you have an XML file like the following:</P>
<PRE>
    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;data&gt;
        &lt;node&gt;val1&lt;/node&gt;
        &lt;node&gt;val2&lt;/node&gt;
        &lt;node&gt;val3&lt;/node&gt;
        &lt;group&gt;
            &lt;node&gt;val4&lt;/node&gt;
            &lt;node&gt;val5&lt;/node&gt;
            &lt;node&gt;val6&lt;/node&gt;
        &lt;/group&gt;
        &lt;node&gt;val7&lt;/node&gt;
        &lt;node&gt;val8&lt;/node&gt;
    &lt;/data&gt;
</PRE>
<P>the node tree for the file would look like the following in memory:</P>
<PRE>
    ?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?
      |
    data
      |
    node - node - node - group - node - node
      |      |      |      |       |      |
    val1   val2   val3     |     val7   val8

                         val4   val5   val6
</PRE>
<P>where &quot;-&quot; is a pointer to the sibling node and &quot;|&quot; is a pointer to
 the first child or parent node.</P>

    mxml_node_t *xml;    /* &lt;?xml ... ?&gt; */
    mxml_node_t *data;   /* &lt;data&gt; */
    mxml_node_t *node;   /* &lt;node&gt; */

        node = mxmlNewElement(data, &quot;node&quot;);
        mxmlNewText(node, 0, &quot;val8&quot;);
</PRE>

<!-- NEED 6 -->
<P>We start by creating the declaration node common to all XML files
 using the <A href="#mxmlNewXML"><TT>mxmlNewXML</TT></A> function:</P>
<PRE>
    xml = mxmlNewXML(&quot;1.0&quot;);
</PRE>
<P>We then create the <TT>&lt;data&gt;</TT> node used for this document using
 the <A href="#mxmlNewElement"><TT>mxmlNewElement</TT></A> function. The
 first argument specifies the parent node (<TT>xml</TT>) while the
 second specifies the element name (<TT>data</TT>):</P>
<PRE>
    data = mxmlNewElement(xml, &quot;data&quot;);
</PRE>
<P>Each <TT>&lt;node&gt;...&lt;/node&gt;</TT> in the file is created using the <TT>
mxmlNewElement</TT> and <A href="#mxmlNewText"><TT>mxmlNewText</TT></A>
 functions. The first argument of <TT>mxmlNewText</TT> specifies the
 parent node (<TT>node</TT>). The second argument specifies whether
 whitespace appears before the text - 0 or false in this case. The last
 argument specifies the actual text to add:</P>
<PRE>
    node = mxmlNewElement(data, &quot;node&quot;);
    mxmlNewText(node, 0, &quot;val1&quot;);
</PRE>
<P>The resulting in-memory XML document can then be saved or processed
 just like one loaded from disk or a string.</P>

<!-- NEED 15 -->
<H2><A NAME="3_4">Loading XML</A></H2>
<P>You load an XML file using the <A href="#mxmlLoadFile"><TT>
mxmlLoadFile</TT></A> function:</P>
<PRE>
    FILE *fp;
    mxml_node_t *tree;

    fp = fopen(&quot;filename.xml&quot;, &quot;r&quot;);
    tree = mxmlLoadFile(NULL, fp,
                        MXML_TEXT_CALLBACK);
    fclose(fp);
</PRE>
<P>The first argument specifies an existing XML parent node, if any.
 Normally you will pass <TT>NULL</TT> for this argument unless you are
 combining multiple XML sources. The XML file must contain a complete
 XML document including the <TT>?xml</TT> element if the parent node is <TT>
NULL</TT>.</P>
<P>The second argument specifies the stdio file to read from, as opened
 by <TT>fopen()</TT> or <TT>popen()</TT>. You can also use <TT>stdin</TT>
 if you are implementing an XML filter program.</P>
<P>The third argument specifies a callback function which returns the
 value type of the immediate children for a new element node: <TT>
MXML_CUSTOM</TT>, <TT>MXML_IGNORE</TT>, <TT>MXML_INTEGER</TT>, <TT>
MXML_OPAQUE</TT>, <TT>MXML_REAL</TT>, or <TT>MXML_TEXT</TT>. Load
 callbacks are described in detail in <A href="#LOAD_CALLBACKS">Chapter
 3</A>. The example code uses the <TT>MXML_TEXT_CALLBACK</TT> constant
 which specifies that all data nodes in the document contain
 whitespace-separated text values. Other standard callbacks include <TT>
MXML_IGNORE_CALLBACK</TT>, <TT>MXML_INTEGER_CALLBACK</TT>, <TT>
MXML_OPAQUE_CALLBACK</TT>, and <TT>MXML_REAL_CALLBACK</TT>.</P>
<P>The <A href="#mxmlLoadString"><TT>mxmlLoadString</TT></A> function
 loads XML node trees from a string:</P>

<!-- NEED 10 -->
<PRE>
    char buffer[8192];
    mxml_node_t *tree;

    ...
    tree = mxmlLoadString(NULL, buffer,
                          MXML_TEXT_CALLBACK);
</PRE>
<P>The first and third arguments are the same as used for <TT>
mxmlLoadFile()</TT>. The second argument specifies the string or
 character buffer to load and must be a complete XML document including
 the <TT>?xml</TT> element if the parent node is <TT>NULL</TT>.</P>

<!-- NEED 15 -->
<H2><A NAME="3_5">Saving XML</A></H2>
<P>You save an XML file using the <A href="#mxmlSaveFile"><TT>
mxmlSaveFile</TT></A> function:</P>
<PRE>
    FILE *fp;
    mxml_node_t *tree;

    fp = fopen(&quot;filename.xml&quot;, &quot;w&quot;);
    mxmlSaveFile(tree, fp, MXML_NO_CALLBACK);
    fclose(fp);
</PRE>
<P>The first argument is the XML node tree to save. It should normally
 be a pointer to the top-level <TT>?xml</TT> node in your XML document.</P>
<P>The second argument is the stdio file to write to, as opened by <TT>
fopen()</TT> or <TT>popen()</TT>. You can also use <TT>stdout</TT> if
 you are implementing an XML filter program.</P>
<P>The third argument is the whitespace callback to use when saving the
 file. Whitespace callbacks are covered in detail in <A href="SAVE_CALLBACKS">
Chapter 3</A>. The previous example code uses the <TT>MXML_NO_CALLBACK</TT>
 constant to specify that no special whitespace handling is required.</P>
<P>The <A href="#mxmlSaveAllocString"><TT>mxmlSaveAllocString</TT></A>,
 and <A href="#mxmlSaveString"><TT>mxmlSaveString</TT></A> functions
 save XML node trees to strings:</P>
<PRE>
    char buffer[8192];
    char *ptr;
    mxml_node_t *tree;

    ...
    ptr = mxmlSaveAllocString(tree, MXML_NO_CALLBACK);
</PRE>
<P>The first and last arguments are the same as used for <TT>
mxmlSaveFile()</TT>. The <TT>mxmlSaveString</TT> function takes pointer
 and size arguments for saving the XML document to a fixed-size buffer,
 while <TT>mxmlSaveAllocString()</TT> returns a string buffer that was
 allocated using <TT>malloc()</TT>.</P>

<H3><A NAME="3_5_1">Controlling Line Wrapping</A></H3>
<P>When saving XML documents, Mini-XML normally wraps output lines at
 column 75 so that the text is readable in terminal windows. The <A href="#mxmlSetWrapMargin">
<TT>mxmlSetWrapMargin</TT></A> function overrides the default wrap
 margin:</P>
<PRE>
    /* Set the margin to 132 columns */
    mxmlSetWrapMargin(132);

    /* Disable wrapping */
    mxmlSetWrapMargin(0);
</PRE>
<H2><A NAME="3_6">Memory Management</A></H2>
<P>Once you are done with the XML data, use the <A href="#mxmlDelete"><TT>
mxmlDelete</TT></A> function to recursively free the memory that is used
 for a particular node or the entire tree:</P>
<PRE>
    mxmlDelete(tree);
</PRE>
<P>You can also use reference counting to manage memory usage. The <A href="#mxmlRetain">
<TT>mxmlRetain</TT></A> and <A href="#mxmlRelease"><TT>mxmlRelease</TT></A>
 functions increment and decrement a node's use count, respectively.
 When the use count goes to 0, <TT>mxmlRelease</TT> will automatically
 call <TT>mxmlDelete</TT> to actually free the memory used by the node
 tree. New nodes automatically start with a use count of 1.</P>

<BR></P>
</LI>
<LI><TT>MXML_DESCEND_FIRST</TT> means that it is OK to descend to the

 You'll normally use this when iterating through direct children of a
 parent node, e.g. all of the &quot;node&quot; and &quot;group&quot; elements under the

<H2><A NAME="4_4">Changing Node Values</A></H2>
<P>All of the examples so far have concentrated on creating and loading
 new XML data nodes. Many applications, however, need to manipulate or

 function call to change a text node to contain the text &quot;new&quot; with
 leading whitespace:</P>
<PRE>
    mxml_node_t *node;

    mxmlSetText(node, 1, &quot;new&quot;);

<H2><A NAME="4_5">Formatted Text</A></H2>
<P>The <A href="#mxmlNewTextf"><TT>mxmlNewTextf()</TT></A> and <A href="#mxmlSetTextf">
<TT>mxmlSetTextf()</TT></A> functions create and change text nodes,
 respectively, using <TT>printf</TT>-style format strings and arguments.
 For example, use the following function call to create a new text node
 containing a constructed filename:</P>
<PRE>
    mxml_node_t *node;

    node = mxmlNewTextf(node, 1, &quot;%s/%s&quot;,

<H2><A NAME="4_6">Indexing</A></H2>
<P>Mini-XML provides functions for managing indices of nodes. The
 current implementation provides the same functionality as <A href="#mxmlFindElement">
<TT>mxmlFindElement()</TT></A>. The advantage of using an index is that
 searching and enumeration of elements is significantly faster. The only
 disadvantage is that each index is a static snapshot of the XML
 document, so indices are not well suited to XML data that is updated
 more often than it is searched. The overhead of creating an index is
 approximately equal to walking the XML document tree. Nodes in the
 index are sorted by element name and attribute value.</P>
<P>Indices are stored in <A href="#mxml_index_t"><TT>mxml_index_t</TT></A>
 structures. The <A href="#mxmlIndexNew"><TT>mxmlIndexNew()</TT></A>
 function creates a new index:</P>
<PRE>
    mxml_node_t *tree;
    mxml_index_t *ind;

    ind = mxmlIndexNew(tree, &quot;element&quot;,
                       &quot;attribute&quot;);
</PRE>
<P>The first argument is the XML node tree to index. Normally this will
 be a pointer to the <TT>?xml</TT> element.</P>
<P>The second argument contains the element to index; passing <TT>NULL</TT>
 indexes all element nodes alphabetically.</P>
<P>The third argument contains the attribute to index; passing <TT>NULL</TT>
 causes only the element name to be indexed.</P>
<P>Once the index is created, the <A href="#mxmlIndexEnum"><TT>
mxmlIndexEnum()</TT></A>, <A href="#mxmlIndexFind"><TT>mxmlIndexFind()</TT>
</A>, and <A href="#mxmlIndexReset"><TT>mxmlIndexReset()</TT></A>
 functions are used to access the nodes in the index. The <A href="#mxmlIndexReset">
<TT>mxmlIndexReset()</TT></A> function resets the &quot;current&quot; node pointer
 in the index, allowing you to do new searches and enumerations on the
 same index. Typically you will call this function prior to your calls
 to <A href="#mxmlIndexEnum"><TT>mxmlIndexEnum()</TT></A> and <A href="#mxmlIndexFind">
<TT>mxmlIndexFind()</TT></A>.</P>
<P>The <A href="#mxmlIndexEnum"><TT>mxmlIndexEnum()</TT></A> function
 enumerates each of the nodes in the index and can be used in a loop as
 follows:</P>
<PRE>
    mxml_node_t *node;

    mxmlIndexReset(ind);

    while ((node = mxmlIndexEnum(ind)) != NULL)
    {
      // do something with node
    }
</PRE>
<P>The <A href="#mxmlIndexFind"><TT>mxmlIndexFind()</TT></A> function
 locates the next occurrence of the named element and attribute value in
 the index. It can be used to find all matching elements in an index, as
 follows:</P>
<PRE>
    mxml_node_t *node;

    mxmlIndexReset(ind);

    while ((node = mxmlIndexFind(ind, &quot;element&quot;,
                                 &quot;attr-value&quot;))
                != NULL)
    {
      // do something with node
    }
</PRE>
<P>The second and third arguments represent the element name and
 attribute value, respectively. A <TT>NULL</TT> pointer is used to
 return all elements or attributes in the index. Passing <TT>NULL</TT>
 for both the element name and attribute value is equivalent to calling <TT>
mxmlIndexEnum</TT>.</P>
<P>When you are done using the index, delete it using the <A href="#mxmlIndexDelete()">
<TT>mxmlIndexDelete()</TT></A> function:</P>
<PRE>
    mxmlIndexDelete(ind);
</PRE>
<H2><A NAME="4_7">SAX (Stream) Loading of Documents</A></H2>
<P>Mini-XML supports an implementation of the Simple API for XML (SAX)
 which allows you to load and process an XML document as a stream of
 nodes. Aside from allowing you to process XML documents of any size,
 the Mini-XML implementation also allows you to retain portions of the
 document in memory for later processing.</P>
<P>The <A href="#mxmlSAXLoad"><TT>mxmlSAXLoadFd</TT></A>, <A href="#mxmlSAXLoadFile">
<TT>mxmlSAXLoadFile</TT></A>, and <A href="#mxmlSAXLoadString"><TT>
mxmlSAXLoadString</TT></A> functions provide the SAX loading APIs. Each
 function works like the corresponding <TT>mxmlLoad</TT> function but
 uses a callback to process each node as it is read.</P>
<P>The callback function receives the node, an event code, and a user
 data pointer you supply:</P>
<PRE>
    void
    sax_cb(mxml_node_t *node,
           mxml_sax_event_t event,
           void *data)
    {
      ... do something ...
    }
</PRE>
<P>The event will be one of the following:</P>
<UL>
<LI><TT>MXML_SAX_CDATA</TT> - CDATA was just read</LI>
<LI><TT>MXML_SAX_COMMENT</TT> - A comment was just read</LI>
<LI><TT>MXML_SAX_DATA</TT> - Data (custom, integer, opaque, real, or
 text) was just read</LI>
<LI><TT>MXML_SAX_DIRECTIVE</TT> - A processing directive was just read</LI>
<LI><TT>MXML_SAX_ELEMENT_CLOSE</TT> - A close element was just read (<TT>
&lt;/element&gt;</TT>)</LI>
<LI><TT>MXML_SAX_ELEMENT_OPEN</TT> - An open element was just read (<TT>
&lt;element&gt;</TT>)</LI>
</UL>
<P>Elements are<EM> released</EM> after the close element is processed.
 All other nodes are released after they are processed. The SAX callback
 can<EM> retain</EM> the node using the <A href="#mxmlRetain"><TT>
mxmlRetain</TT></A> function. For example, the following SAX callback
 will retain all nodes, effectively simulating a normal in-memory load:</P>
<PRE>
    void
    sax_cb(mxml_node_t *node,
           mxml_sax_event_t event,
           void *data)
    {
      if (event != MXML_SAX_ELEMENT_CLOSE)
        mxmlRetain(node);
    }
</PRE>
<P>More typically the SAX callback will only retain a small portion of
 the document that is needed for post-processing. For example, the
 following SAX callback will retain the title and headings in an XHTML
 file. It also retains the (parent) elements like <TT>&lt;html&gt;</TT>, <TT>
&lt;head&gt;</TT>, and <TT>&lt;body&gt;</TT>, and processing directives like <TT>
&lt;?xml ... ?&gt;</TT> and <TT>&lt;!DOCTYPE ... &gt;</TT>:</P>

<PRE>
    void
    sax_cb(mxml_node_t *node,
           mxml_sax_event_t event,

    {
      if (event == MXML_SAX_ELEMENT_OPEN)
      {
       /*

</PRE>
<P>The resulting skeleton document tree can then be searched just like
 one loaded using the <TT>mxmlLoad</TT> functions. For example, a filter
 that reads an XHTML document from stdin and then shows the title and
 headings in the document would look like:</P>

<H1 align="right"><A name="MXMLDOC"><IMG align="right" alt="4" height="100"
hspace="10" src="4.gif" width="100"></A>Using the mxmldoc Utility</H1>
<P>This chapter describes how to use <TT>mxmldoc(1)</TT> program to
 automatically generate documentation from C and C++ source files.</P>
<H2><A NAME="5_1">The Basics</A></H2>
<P>Originally developed to generate the Mini-XML and CUPS API
 documentation, <TT>mxmldoc</TT> is now a general-purpose utility which
 scans C and C++ source files to produce HTML and man page documentation
 along with an XML file representing the functions, types, and
 definitions in those source files. Unlike popular documentation
 generators like Doxygen or Javadoc, <TT>mxmldoc</TT> uses in-line
 comments rather than comment headers, allowing for more &quot;natural&quot; code
 documentation.</P>
<P>By default, <TT>mxmldoc</TT> produces HTML documentation. For
 example, the following command will scan all of the C source and header
 files in the current directory and produce a HTML documentation file
 called<VAR> filename.html</VAR>:</P>
<PRE>
    <KBD>mxmldoc *.h *.c &gt;filename.html ENTER</KBD>
</PRE>
<P>You can also specify an XML file to create which contains all of the
 information from the source files. For example, the following command
 creates an XML file called<VAR> filename.xml</VAR> in addition to the
 HTML file:</P>
<PRE>
    <KBD>mxmldoc filename.xml *.h *.c &gt;filename.html ENTER</KBD>
</PRE>
<P>The <TT>--no-output</TT> option disables the normal HTML output:</P>
<PRE>
    <KBD>mxmldoc --no-output filename.xml *.h *.c ENTER</KBD>
</PRE>
<P>You can then run <TT>mxmldoc</TT> again with the XML file alone to
 generate the HTML documentation:</P>
<PRE>
    <KBD>mxmldoc filename.xml &gt;filename.html ENTER</KBD>
</PRE>
<H3><A NAME="5_1_1">Creating Man Pages</A></H3>
<P>The <TT>--man filename</TT> option tells <TT>mxmldoc</TT> to create a
 man page instead of HTML documentation, for example:</P>
<PRE>
    <KBD>mxmldoc --man filename filename.xml \
        &gt;filename.man ENTER</KBD>

    <KBD>mxmldoc --man filename *.h *.c \
        &gt;filename.man ENTER</KBD>
</PRE>
<H3><A NAME="5_1_2">Creating Xcode Documentation Sets</A></H3>
<P>The <TT>--docset directory.docset</TT> option tells <TT>mxmldoc</TT>
 to create an Xcode documentation set containing the HTML documentation,
 for example:</P>
<PRE>
    <KBD>mxmldoc --docset foo.docset *.h *.c foo.xml ENTER</KBD>
</PRE>
<P>Xcode documentation sets can only be built on Mac OS X with Xcode 3.0
 or higher installed.</P>
<H2><A NAME="5_2">Commenting Your Code</A></H2>
<P>As noted previously, <TT>mxmldoc</TT> looks for in-line comments to
 describe the functions, types, and constants in your code. <TT>Mxmldoc</TT>
 will document all public names it finds in your source files - any
 names starting with the underscore character (_) or names that are
 documented with the <A HREF="#ATDIRECTIVES">@private@</A> directive are
 treated as private and are not documented.</P>
<P>Comments appearing directly before a function or type definition are
 used to document that function or type. Comments appearing after
 argument, definition, return type, or variable declarations are used to
 document that argument, definition, return type, or variable. For
 example, the following code excerpt defines a key/value structure and a
 function that creates a new instance of that structure:</P>
<PRE>
    /* A key/value pair. This is used with the
       dictionary structure. */

    struct keyval
    {
      char *key; /* Key string */
      char *val; /* Value string */
    };

    /* Create a new key/value pair. */

    struct keyval * /* New key/value pair */
    new_keyval(
        const char *key, /* Key string */
	const char *val) /* Value string */
    {
      ...
    }
</PRE>
<P><TT>Mxmldoc</TT> also knows to remove extra asterisks (*) from the
 comment string, so the comment string:</P>
<PRE>
    /*
     * Compute the value of PI.
     *
     * The function connects to an Internet server
     * that streams audio of mathematical monks
     * chanting the first 100 digits of PI.
     */
</PRE>
<P>will be shown as:</P>
<PRE>
    Compute the value of PI.

    The function connects to an Internet server
    that streams audio of mathematical monks
    chanting the first 100 digits of PI.
</PRE>
<P><A name="ATDIRECTIVES">Comments</A> can also include the following
 special <TT>@name ...@</TT> directive strings:</P>
<UL>
<LI><TT>@deprecated@</TT> - flags the item as deprecated to discourage
 its use</LI>
<LI><TT>@private@</TT> - flags the item as private so it will not be
 included in the documentation</LI>
<LI><TT>@since ...@</TT> - flags the item as new since a particular
 release. The text following the <TT>@since</TT> up to the closing <TT>@</TT>
 is highlighted in the generated documentation, e.g. <TT>@since Mini-XML
 2.7@</TT>.</LI>
</UL>

<!-- NEED 10 -->
<H2><A NAME="5_3">Titles, Sections, and Introductions</A></H2>
<P><TT>Mxmldoc</TT> also provides options to set the title, section, and
 introduction text for the generated documentation. The <TT>--title text</TT>
 option specifies the title for the documentation. The title string is
 usually put in quotes:</P>
<PRE>
    <KBD>mxmldoc filename.xml \
        --title &quot;My Famous Documentation&quot; \
        &gt;filename.html ENTER</KBD>
</PRE>
<P>The <TT>--section name</TT> option specifies the section for the
 documentation. For HTML documentation, the name is placed in a HTML
 comment such as:</P>
<PRE>
    &lt;!-- SECTION: name --&gt;
</PRE>
<P>For man pages, the section name is usually just a number (&quot;3&quot;), or a
 number followed by a vendor name (&quot;3acme&quot;). The section name is used in
 the <TT>.TH</TT> directive in the man page:</P>
<PRE>
    .TH mylibrary 3acme &quot;My Title&quot; ...
</PRE>
<P>The default section name for man page output is &quot;3&quot;. There is no
 default section name for HTML output.</P>
<P>Finally, the <TT>--intro filename</TT> option specifies a file to
 embed after the title and section but before the generated
 documentation. For HTML documentation, the file must consist of valid
 HTML without the usual <TT>DOCTYPE</TT>, <TT>html</TT>, and <TT>body</TT>
 elements. For man page documentation, the file must consist of valid <TT>
nroff(1)</TT> text.</P>

<P align="center">Version 2, June 1991
<BR> Copyright (C) 1991 Free Software Foundation, Inc.
<BR> 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
<BR> Everyone is permitted to copy and distribute verbatim copies of
 this license document, but changing it is not allowed.
<BR> [This is the first released version of the library GPL. It is
 numbered 2 because it goes with version 2 of the ordinary GPL.]</P>
<P><B>Preamble</B></P>
<P>The licenses for most software are designed to take away your freedom
 to share and change it. By contrast, the GNU General Public Licenses
 are intended to guarantee your freedom to share and change free
 software--to make sure the software is free for all its users.</P>
<P>This license, the Library General Public License, applies to some
 specially designated Free Software Foundation software, and to any
 other libraries whose authors decide to use it. You can use it for your
 libraries, too.</P>
<P>When we speak of free software, we are referring to freedom, not
 price. Our General Public Licenses are designed to make sure that you
 have the freedom to distribute copies of free software (and charge for
 this service if you wish), that you receive source code or can get it
 if you want it, that you can change the software or use pieces of it in
 new free programs; and that you know you can do these things.</P>
<P>To protect your rights, we need to make restrictions that forbid
 anyone to deny you these rights or to ask you to surrender the rights.
 These restrictions translate to certain responsibilities for you if you
 distribute copies of the library, or if you modify it.</P>
<P>For example, if you distribute copies of the library, whether gratis
 or for a fee, you must give the recipients all the rights that we gave
 you. You must make sure that they, too, receive or can get the source
 code. If you link a program with the library, you must provide complete
 object files to the recipients so that they can relink them with the
 library, after making changes to the library and recompiling it. And
 you must show them these terms so they know their rights.</P>
<P>Our method of protecting your rights has two steps: (1) copyright the
 library, and (2) offer you this license which gives you legal
 permission to copy, distribute and/or modify the library.</P>
<P>Also, for each distributor's protection, we want to make certain that
 everyone understands that there is no warranty for this free library.
 If the library is modified by someone else and passed on, we want its
 recipients to know that what they have is not the original version, so
 that any problems introduced by others will not reflect on the original
 authors' reputations.</P>
<P>Finally, any free program is threatened constantly by software
 patents. We wish to avoid the danger that companies distributing free
 software will individually obtain patent licenses, thus in effect
 transforming the program into proprietary software. To prevent this, we
 have made it clear that any patent must be licensed for everyone's free
 use or not licensed at all.</P>
<P>Most GNU software, including some libraries, is covered by the
 ordinary GNU General Public License, which was designed for utility
 programs. This license, the GNU Library General Public License, applies
 to certain designated libraries. This license is quite different from
 the ordinary one; be sure to read it in full, and don't assume that
 anything in it is the same as in the ordinary license.</P>
<P>The reason we have a separate public license for some libraries is
 that they blur the distinction we usually make between modifying or
 adding to a program and simply using it. Linking a program with a
 library, without changing the library, is in some sense simply using
 the library, and is analogous to running a utility program or
 application program. However, in a textual and legal sense, the linked
 executable is a combined work, a derivative of the original library,
 and the ordinary General Public License treats it as such.</P>
<P>Because of this blurred distinction, using the ordinary General
 Public License for libraries did not effectively promote software
 sharing, because most developers did not use the libraries. We
 concluded that weaker conditions might promote sharing better.</P>
<P>However, unrestricted linking of non-free programs would deprive the
 users of those programs of all benefit from the free status of the
 libraries themselves. This Library General Public License is intended
 to permit developers of non-free programs to use free libraries, while
 preserving your freedom as a user of such programs to change the free
 libraries that are incorporated in them. (We have not seen how to
 achieve this as regards changes in header files, but we have achieved
 it as regards changes in the actual functions of the Library.) The hope
 is that this will lead to faster development of free libraries.</P>
<P>The precise terms and conditions for copying, distribution and
 modification follow. Pay close attention to the difference between a
 &quot;work based on the libary&quot; and a &quot;work that uses the library&quot;. The
 former contains code derived from the library, while the latter only
 works together with the library.</P>
<P>Note that it is possible for a library to be covered by the ordinary
 General Public License rather than by this special one.</P>
<P align="center"><B>TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND
 MODIFICATION</B></P>
<P><STRONG>0.</STRONG> This License Agreement applies to any software
 library which contains a notice placed by the copyright holder or other
 authorized party saying it may be distributed under the terms of this
 Library General Public License (also called &quot;this License&quot;). Each
 licensee is addressed as &quot;you&quot;.</P>
<P>A &quot;library&quot; means a collection of software functions and/or data
 prepared so as to be conveniently linked with application programs
 (which use some of those functions and data) to form executables.</P>
<P>The &quot;Library&quot;, below, refers to any such software library or work
 which has been distributed under these terms. A &quot;work based on the
 Library&quot; means either the Library or any derivative work under
 copyright law: that is to say, a work containing the Library or a
 portion of it, either verbatim or with modifications and/or translated
 straightforwardly into another language. (Hereinafter, translation is
 included without limitation in the term &quot;modification&quot;.)</P>
<P>&quot;Source code&quot; for a work means the preferred form of the work for
 making modifications to it. For a library, complete source code means
 all the source code for all modules it contains, plus any associated
 interface definition files, plus the scripts used to control
 compilation and installation of the library.</P>
<P>Activities other than copying, distribution and modification are not
 covered by this License; they are outside its scope. The act of running
 a program using the Library is not restricted, and output from such a
 program is covered only if its contents constitute a work based on the
 Library (independent of the use of the Library in a tool for writing
 it). Whether that is true depends on what the Library does and what the
 program that uses the Library does.</P>
<P><STRONG>1.</STRONG> You may copy and distribute verbatim copies of
 the Library's complete source code as you receive it, in any medium,
 provided that you conspicuously and appropriately publish on each copy
 an appropriate copyright notice and disclaimer of warranty; keep intact
 all the notices that refer to this License and to the absence of any
 warranty; and distribute a copy of this License along with the Library.</P>
<P>You may charge a fee for the physical act of transferring a copy, and
 you may at your option offer warranty protection in exchange for a fee.</P>
<P><STRONG>2.</STRONG> You may modify your copy or copies of the Library
 or any portion of it, thus forming a work based on the Library, and
 copy and distribute such modifications or work under the terms of
 Section 1 above, provided that you also meet all of these conditions:</P>
<UL>
<P><STRONG>a)</STRONG> The modified work must itself be a software
 library.</P>
<P><STRONG>b)</STRONG> You must cause the files modified to carry
 prominent notices stating that you changed the files and the date of
 any change.</P>
<P><STRONG>c)</STRONG> You must cause the whole of the work to be
 licensed at no charge to all third parties under the terms of this
 License.</P>
<P><STRONG>d)</STRONG> If a facility in the modified Library refers to a
 function or a table of data to be supplied by an application program
 that uses the facility, other than as an argument passed when the
 facility is invoked, then you must make a good faith effort to ensure
 that, in the event an application does not supply such function or
 table, the facility still operates, and performs whatever part of its
 purpose remains meaningful.</P>
<P>(For example, a function in a library to compute square roots has a
 purpose that is entirely well-defined independent of the application.
 Therefore, Subsection 2d requires that any application-supplied
 function or table used by this function must be optional: if the
 application does not supply it, the square root function must still
 compute square roots.)</P>
</UL>
<P>These requirements apply to the modified work as a whole. If
 identifiable sections of that work are not derived from the Library,
 and can be reasonably considered independent and separate works in
 themselves, then this License, and its terms, do not apply to those
 sections when you distribute them as separate works. But when you
 distribute the same sections as part of a whole which is a work based
 on the Library, the distribution of the whole must be on the terms of
 this License, whose permissions for other licensees extend to the
 entire whole, and thus to each and every part regardless of who wrote
 it.</P>
<P>Thus, it is not the intent of this section to claim rights or contest
 your rights to work written entirely by you; rather, the intent is to
 exercise the right to control the distribution of derivative or
 collective works based on the Library.</P>
<P>In addition, mere aggregation of another work not based on the
 Library with the Library (or with a work based on the Library) on a
 volume of a storage or distribution medium does not bring the other
 work under the scope of this License.</P>
<P><STRONG>3.</STRONG> You may opt to apply the terms of the ordinary
 GNU General Public License instead of this License to a given copy of
 the Library. To do this, you must alter all the notices that refer to
 this License, so that they refer to the ordinary GNU General Public
 License, version 2, instead of to this License. (If a newer version
 than version 2 of the ordinary GNU General Public License has appeared,
 then you can specify that version instead if you wish.) Do not make any
 other change in these notices.</P>
<P>Once this change is made in a given copy, it is irreversible for that
 copy, so the ordinary GNU General Public License applies to all
 subsequent copies and derivative works made from that copy.</P>
<P>This option is useful when you wish to copy part of the code of the
 Library into a program that is not a library.</P>
<P><STRONG>4.</STRONG> You may copy and distribute the Library (or a
 portion or derivative of it, under Section 2) in object code or
 executable form under the terms of Sections 1 and 2 above provided that
 you accompany it with the complete corresponding machine-readable
 source code, which must be distributed under the terms of Sections 1
 and 2 above on a medium customarily used for software interchange.</P>
<P>If distribution of object code is made by offering access to copy
 from a designated place, then offering equivalent access to copy the
 source code from the same place satisfies the requirement to distribute
 the source code, even though third parties are not compelled to copy
 the source along with the object code.</P>
<P><STRONG>5.</STRONG> A program that contains no derivative of any
 portion of the Library, but is designed to work with the Library by
 being compiled or linked with it, is called a &quot;work that uses the
 Library&quot;. Such a work, in isolation, is not a derivative work of the
 Library, and therefore falls outside the scope of this License.</P>
<P>However, linking a &quot;work that uses the Library&quot; with the Library
 creates an executable that is a derivative of the Library (because it
 contains portions of the Library), rather than a &quot;work that uses the
 library&quot;. The executable is therefore covered by this License. Section
 6 states terms for distribution of such executables.</P>
<P>When a &quot;work that uses the Library&quot; uses material from a header file
 that is part of the Library, the object code for the work may be a
 derivative work of the Library even though the source code is not.
 Whether this is true is especially significant if the work can be
 linked without the Library, or if the work is itself a library. The
 threshold for this to be true is not precisely defined by law.</P>
<P>If such an object file uses only numerical parameters, data structure
 layouts and accessors, and small macros and small inline functions (ten
 lines or less in length), then the use of the object file is
 unrestricted, regardless of whether it is legally a derivative work.
 (Executables containing this object code plus portions of the Library
 will still fall under Section 6.)</P>
<P>Otherwise, if the work is a derivative of the Library, you may
 distribute the object code for the work under the terms of Section 6.
 Any executables containing that work also fall under Section 6, whether
 or not they are linked directly with the Library itself.</P>
<P><STRONG>6.</STRONG> As an exception to the Sections above, you may
 also compile or link a &quot;work that uses the Library&quot; with the Library to
 produce a work containing portions of the Library, and distribute that
 work under terms of your choice, provided that the terms permit
 modification of the work for the customer's own use and reverse
 engineering for debugging such modifications.</P>
<P>You must give prominent notice with each copy of the work that the
 Library is used in it and that the Library and its use are covered by
 this License. You must supply a copy of this License. If the work
 during execution displays copyright notices, you must include the
 copyright notice for the Library among them, as well as a reference
 directing the user to the copy of this License. Also, you must do one
 of these things:</P>
<UL><STRONG> a)</STRONG> Accompany the work with the complete
 corresponding machine-readable source code for the Library including
 whatever changes were used in the work (which must be distributed under
 Sections 1 and 2 above); and, if the work is an executable linked with
 the Library, with the complete machine-readable &quot;work that uses the
 Library&quot;, as object code and/or source code, so that the user can
 modify the Library and then relink to produce a modified executable
 containing the modified Library. (It is understood that the user who
 changes the contents of definitions files in the Library will not
 necessarily be able to recompile the application to use the modified
 definitions.)
<P><STRONG>b)</STRONG> Accompany the work with a written offer, valid
 for at least three years, to give the same user the materials specified
 in Subsection 6a, above, for a charge no more than the cost of
 performing this distribution.</P>
<P><STRONG>c)</STRONG> If distribution of the work is made by offering
 access to copy from a designated place, offer equivalent access to copy
 the above specified materials from the same place.</P>
<P><STRONG>d)</STRONG> Verify that the user has already received a copy
 of these materials or that you have already sent this user a copy.</P>
</UL>
<P>For an executable, the required form of the &quot;work that uses the
 Library&quot; must include any data and utility programs needed for
 reproducing the executable from it. However, as a special exception,
 the source code distributed need not include anything that is normally
 distributed (in either source or binary form) with the major components
 (compiler, kernel, and so on) of the operating system on which the
 executable runs, unless that component itself accompanies the
 executable.</P>
<P>It may happen that this requirement contradicts the license
 restrictions of other proprietary libraries that do not normally
 accompany the operating system. Such a contradiction means you cannot
 use both them and the Library together in an executable that you
 distribute.</P>
<P><STRONG>7.</STRONG> You may place library facilities that are a work
 based on the Library side-by-side in a single library together with
 other library facilities not covered by this License, and distribute
 such a combined library, provided that the separate distribution of the
 work based on the Library and of the other library facilities is
 otherwise permitted, and provided that you do these two things:</P>
<UL><STRONG> a)</STRONG> Accompany the combined library with a copy of
 the same work based on the Library, uncombined with any other library
 facilities. This must be distributed under the terms of the Sections
 above.
<P><STRONG>b)</STRONG> Give prominent notice with the combined library
 of the fact that part of it is a work based on the Library, and
 explaining where to find the accompanying uncombined form of the same
 work.</P>
</UL>
<P><STRONG>8.</STRONG> You may not copy, modify, sublicense, link with,
 or distribute the Library except as expressly provided under this
 License. Any attempt otherwise to copy, modify, sublicense, link with,
 or distribute the Library is void, and will automatically terminate
 your rights under this License. However, parties who have received
 copies, or rights, from you under this License will not have their
 licenses terminated so long as such parties remain in full compliance.</P>
<P><STRONG>9.</STRONG> You are not required to accept this License,
 since you have not signed it. However, nothing else grants you
 permission to modify or distribute the Library or its derivative works.
 These actions are prohibited by law if you do not accept this License.
 Therefore, by modifying or distributing the Library (or any work based
 on the Library), you indicate your acceptance of this License to do so,
 and all its terms and conditions for copying, distributing or modifying
 the Library or works based on it.</P>
<P><STRONG>10.</STRONG> Each time you redistribute the Library (or any
 work based on the Library), the recipient automatically receives a
 license from the original licensor to copy, distribute, link with or
 modify the Library subject to these terms and conditions. You may not
 impose any further restrictions on the recipients' exercise of the
 rights granted herein. You are not responsible for enforcing compliance
 by third parties to this License.</P>
<P><STRONG>11.</STRONG> If, as a consequence of a court judgment or
 allegation of patent infringement or for any other reason (not limited
 to patent issues), conditions are imposed on you (whether by court
 order, agreement or otherwise) that contradict the conditions of this
 License, they do not excuse you from the conditions of this License. If
 you cannot distribute so as to satisfy simultaneously your obligations
 under this License and any other pertinent obligations, then as a
 consequence you may not distribute the Library at all. For example, if
 a patent license would not permit royalty-free redistribution of the
 Library by all those who receive copies directly or indirectly through
 you, then the only way you could satisfy both it and this License would
 be to refrain entirely from distribution of the Library.</P>
<P>If any portion of this section is held invalid or unenforceable under
 any particular circumstance, the balance of the section is intended to
 apply, and the section as a whole is intended to apply in other
 circumstances.</P>
<P>It is not the purpose of this section to induce you to infringe any
 patents or other property right claims or to contest validity of any
 such claims; this section has the sole purpose of protecting the
 integrity of the free software distribution system which is implemented
 by public license practices. Many people have made generous
 contributions to the wide range of software distributed through that
 system in reliance on consistent application of that system; it is up
 to the author/donor to decide if he or she is willing to distribute
 software through any other system and a licensee cannot impose that
 choice.</P>
<P>This section is intended to make thoroughly clear what is believed to
 be a consequence of the rest of this License.</P>
<P><STRONG>12.</STRONG> If the distribution and/or use of the Library is
 restricted in certain countries either by patents or by copyrighted
 interfaces, the original copyright holder who places the Library under
 this License may add an explicit geographical distribution limitation
 excluding those countries, so that distribution is permitted only in or
 among countries not thus excluded. In such case, this License
 incorporates the limitation as if written in the body of this License.</P>
<P><STRONG>13.</STRONG> The Free Software Foundation may publish revised
 and/or new versions of the Library General Public License from time to
 time. Such new versions will be similar in spirit to the present
 version, but may differ in detail to address new problems or concerns.</P>
<P>Each version is given a distinguishing version number. If the Library
 specifies a version number of this License which applies to it and &quot;any
 later version&quot;, you have the option of following the terms and
 conditions either of that version or of any later version published by
 the Free Software Foundation. If the Library does not specify a license
 version number, you may choose any version ever published by the Free
 Software Foundation.</P>
<P><STRONG>14.</STRONG> If you wish to incorporate parts of the Library
 into other free programs whose distribution conditions are incompatible
 with these, write to the author to ask for permission. For software
 which is copyrighted by the Free Software Foundation, write to the Free
 Software Foundation; we sometimes make exceptions for this. Our
 decision will be guided by the two goals of preserving the free status
 of all derivatives of our free software and of promoting the sharing
 and reuse of software generally.</P>
<P align="center"><B>NO WARRANTY</B></P>
<P><STRONG>15.</STRONG> BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE,
 THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY
 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
 HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY &quot;AS IS&quot; WITHOUT
 WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
 LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
 PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
 OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU
 ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</P>
<P><STRONG>16.</STRONG> IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR
 AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO
 MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE
 LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL
 OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
 DAMAGES.</P>
<P align="center"><B>END OF TERMS AND CONDITIONS</B></P>
<P><B>How to Apply These Terms to Your New Libraries</B></P>
<P>If you develop a new library, and you want it to be of the greatest
 possible use to the public, we recommend making it free software that
 everyone can redistribute and change. You can do so by permitting
 redistribution under these terms (or, alternatively, under the terms of
 the ordinary General Public License).</P>
<P>To apply these terms, attach the following notices to the library. It
 is safest to attach them to the start of each source file to most
 effectively convey the exclusion of warranty; and each file should have
 at least the &quot;copyright&quot; line and a pointer to where the full notice is
 found.</P>
<UL>
<P><VAR>one line to give the library's name and an idea of what it does.</VAR>

 it under the terms of the GNU Lesser General Public License as

<P>This library is distributed in the hope that it will be useful, but
 WITHOUT ANY WARRANTY; without even the implied warranty of
 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser
 General Public License for more details.</P>

<P>Also add information on how to contact you by electronic and paper
 mail.</P>
<P>You should also get your employer (if you work as a programmer) or
 your school, if any, to sign a &quot;copyright disclaimer&quot; for the library,
 if necessary. Here is a sample; alter the names:</P>
