+/**
+ * Provides classes for converting Palm database data to/from a
+ * {@code PalmDocument} object, which can be used by the framework.
+ *
+ * <p>This package provides classes that handle the writing of data to an
+ * {@code OutputStream} object for the {@link
+ * org.openoffice.xmerge.DocumentSerializer DocumentSerializer} interface for;
+ * as well as the reading of data from an {@code InputStream} object for the
+ * framework's {@link org.openoffice.xmerge.DocumentDeserializer
+ * DocumentDeserializer} interface. Both these framework interfaces are simply
+ * converters from server-side documents to device specific documents and
+ * vice-versa.
+ * Since all Palm databases have a general record oriented format, a Palm
+ * database converter specific I/O stream format is specified for the Palm sync
+ * client application to handle the byte stream in a generic way.
+ * This also means that Palm database converters should read and/or write using
+ * this I/O stream format as specified in the next section.</p>
+ *
+ * <a name="streamformat"></a>
+ *
+ * <h2>Palm database converter specific I/O stream format</h2>
+ *
+ * <p>Note that the format of the byte stream is not exactly that of a PDB file
+ * encoding. It does not need to contain the PDB header information nor record
+ * indices section. Instead, it contains the following ...</p>
+ * <pre>
+ * set header
+ * 4 bytes - creator id
+ * 4 bytes - type id
+ * 2 bytes - PDB header version
+ * 2 bytes - PDB header attribute
+ * unsigned 2 bytes - number of PDB data to follow
+ *
+ * for each PDB,
+ * 32 bytes - name of PDB i
+ * unsigned 2 bytes - number of records in PDB i
+ *
+ * for each record contained in PDB i,
+ * 1 byte - record attributes
+ * unsigned 2 bytes - size of record j in PDB i
+ * x bytes - data
+ * </pre>
+ *
+ * <p>Note that each PDB section is appended by another if there is more than
+ * one.</p>
+ *
+ * <p>Since the {@code PalmDocument} class takes care of the writing and reading
+ * of this format through its {@code write} and {@code read} methods,
+ * respectively, this format shall also be referred to as the <b>PalmDocument
+ * stream format</b>.</p>
+ *
+ * <h2>Usage of the classes for the specified I/O stream</h2>
+ *
+ * <p>When converting from a server document to device document(s), the
+ * framework requires writing the device document(s) to an {@code OutputStream}
+ * object via the {@code DocumentSerializer} interface. Note that a single
+ * server document may be converted into multiple PDB's on the Palm device.
+ * Each worksheet in the document is converted into a {@code PalmDocument}.
+ * Thus, if there is more than one worksheet in the document, more than one
+ * {@code PalmDocument} will be produced by the {@code DocumentSerializer}.</p>
+ *
+ * <p>A {@code DocumentSerializer} creates a {@code ConvertData} object, which
+ * contains all of the {@code PalmDocuments}. The {@link
+ * org.openoffice.xmerge.converter.palm.PalmDocument#write write} method to
+ * write to the given {@code OutputStream}.
+ * The {@code PalmDocument} object will take care of writing the data in the
+ * <a href=#streamformat>specified format</a>.</p>
+ *
+ * <p>A {@code DocumentDeserializer} can use the {@code PalmDocument} object's
+ * {@link org.openoffice.xmerge.converter.palm.PalmDocument#read read} method
+ * to fill in all the {@code PalmDocument} object's data.</p>
+ *
+ * <h2>PDB file encoding/decoding</h2>
+ *
+ * <p>The {@code PalmDocument} object's read and write functions are provided by
+ * the {@code PdbDecoder} and {@code PdbEncoder} objects.
+ * The {@code PdbEncoder} class provides the functionality of encoding a
+ * {@code PalmDB} object into an {@code InputStream}, while the
+ * {@code PdbDecoder} class provides the functionality of decoding a PDB file
+ * into an {@code OutputStream}.</p>
+ *
+ * <p>Refer to the class description of each for usage.</p>
+ *
+ * <h2>Important Note</h2>
+ *
+ * <p>Methods in these classes are not thread safe for performance reasons.
+ * Users of these classes will have to make sure that the usage of these classes
+ * are done in a proper manner. Possibly more on this later.</p>
+ *
+ * <h2>TODO list</h2>
+ *
+ * <ol>
+ * <li>Merge the PalmDB, PdbDecoder and PdbEncoder classes into the PalmDocument
+ * class.</li>
+ * <li>After reading more on the palm file format spec, I realized that there
+ * are certain optional fields that may need to be addressed still, like the
+ * appInfo block and sortInfo block.</li>
+ * <li>The current PdbDecoder only returns a PalmDB object. There are other
+ * information that we may want to expose from the PDB decoding process.</li>
+ * <li>Investigate on different language encoding on the Palm and how that
+ * affects the PDB name.</li>
+ * </ol>

+ *
+ * <p>This converter does not currently support merge.</p>
+ *
+ * <h2>XSLT Transformation</h2>
+ *
+ * <p>The converter makes use of one or more XSLT style sheets, which are used
+ * in the DocumentSerializer and DocumentDeserializer, to perform the actual
+ * translations. The location of these stylesheets is extracted from the
+ * {@link org.openoffice.xmerge.util.registry.ConverterInfo ConverterInfo} data
+ * structure, and are specified using the optional converter-XSLT-serialize and
+ * converter-XSLT-deserialize tags in a plug-ins converter.xml file. Please
+ * refer to the SDK document for more information about how to implement a
+ * Plug-in Configuration XML File for a specific plug-in.
+ * A sample OpenOffice to HTML stylesheet and HTML to OpenOffice stylesheet, has
+ * been provided as a sample implementation. The converter also makes use of an
+ * XsltPlugin.properties file, which may be edited by the user to provide
+ * MIME-TYPE to file extension mappings. This file is used by the
+ * {@link org.openoffice.xmerge.converter.xml.xslt.PluginFactoryImpl
+ * getDeviceFileExtension} method.</p>
+ *
+ * <h2>TODO list</h2>
+ *
+ * <ol>
+ * <li>Expand XSLT style sheets to support more office/HTML capabilities</li>
+ * <li>Add support for certain character codes, such as {@literal &} which
+ * currently causes the transformer to break.</li>
+ * <li>Change the DocumentDeserializer transformer, so that the DOMResult is
+ * serialized using the xalan serializer and create an SxwDocument from the
+ * result</li>

+/**
+ * Provides interfaces for converting between two {@code Document} formats, and
+ * supports a {@literal "merge"} interface for merging back changes from a
+ * {@literal "lossy"} format back into a rich format.
+ *
+ * <p>The {@link org.openoffice.xmerge.Convert Convert} object encapsulates the
+ * conversion of one format to/from another format. The user requests a
+ * {@code Convert} object via the {@code ConverterFactory}.</p>
+ *
+ * <p> The {@code Convert} class encapsulates a specific plug-in.
+ * A plug-in can support deserialization (convert from {@literal "Device"} to
+ * {@literal "Office"}) and/or serialization (convert from {@literal "Office"}
+ * to {@literal "Device"}). If a plug-in supports both deserialization and
+ * serialization, then it can also support {@literal "merge"}.</p>
+ *
+ * <p>To support conversions where a single input {@code Document} can create
+ * multiple output {@code Document} objects, data is passed in and out of the
+ * conversion functions via a {@code ConvertData"} object.
+ * This {@code ConvertData} can contain one or more {@code Document} objects.
+ * It is assumed that the client will know when to pass multiple files into a
+ * specific plug-in, and that the plug-in will know how to handle the multiple
+ * files.</p>
+ *
+ * <p>Merging is useful when converting from a rich {@code Document} format to
+ * a more lossy format. Then the user may modify the {@code Document} in the
+ * lossy format, and {@literal "merge"} those changes back into the original
+ * {@literal "rich"} {@code Document}.
+ * Each merge implementation provides a {@code ConverterCapabilities}
+ * implementation so that the merge logic knows what changes from the
+ * {@literal "lossy"} format to merge into the original {@literal "rich"}
+ * {@code Document}.</p>
+ *
+ * <p>Each plug-in must be registered via the singleton {@code ConverterInfoMgr}
+ * object via its {@link
+ * org.openoffice.xmerge.util.registry.ConverterInfoMgr#addPlugIn addPlugIn}
+ * method.</p>
+ *
+ * <h2>Providing implementations</h2>
+ *
+ * <p>The plug-in implementation must include the {@code getDeviceDocument} and
+ * {@code getOfficeDocument} methods. These functions need to return the
+ * appropriate type of {@code Document} for the plug-in. It may be necessary to
+ * create a new implementation of the {@code Document} interface if one does not
+ * exist that meets the needs of the plug-in.</p>
+ *
+ * <p>Currently, base implementations for working with StarWriter XML
+ * {@code Document} objects are available via the
+ * <a href="converter/xml/sxc/package-summary.html#package_description">
+ * org.openoffice.xmerge.xml.sxw</a> package, and StarCalc XML {@code Document}
+ * objects via the
+ * <a href="converter/xml/sxw/package-summary.html#package_description">
+ * org.openoffice.xmerge.xml.sxc</a> package.</p>
+ *
+ * <h2>TODO/IDEAS list</h2>
+ *
+ * <ol>
+ * <li>An idea is to combine the {@code ConvertData} and the {@code Convert}
+ * classes, so that a {@code ConvertData} knows what it can convert into and
+ * whether or not it can merge.
+ * Then a user would call convert/merge methods on the {@code ConvertData}
+ * class, which returns a {@code ConvertData} object that likewise knows what
+ * it can convert/merge into.</li>
+ * <li>{@code DocumentSerialize} constructors and the
+ * {@code DocumentDeserializer.deserializer} method could pass in a
+ * {@code ConvertData} object rather than assuming a single {@code Document}
+ * will represent a {@literal "rich"} {@code Document}.</li>
+ * <li>May need to add a {@code PluginFactory.setProperties} method for adding
+ * properties specific to each converter.</li>
+ * </ol>

+/**
+ * Provides an interface for plug-in registration.
+ *
+ * <p>Each plug-in must have a corresponding Plug-in Configuration XML File
+ * which is named converter.xml. If the plug-in is stored in a jarfile, this
+ * converter.xml file is typically stored in the following location in the
+ * jarfile:</p>
+ *
+ * <blockquote>META-INF/converter.xml</blockquote>
+ *
+ * <p>The Plug-in Configuration XML File must validate against the converter.dtd
+ * file provided with this package. Since a jarfile can contain multiple
+ * plug-ins, this DTD supports specifying multiple plug-ins per jarfile. Please
+ * refer to the SDK document for more information about how to implement a
+ * Plug-in Configuration XML File for a specific plug-in.</p>
+ *
+ * <p>All information in the Plug-in Configuration XML File is bundled into one
+ * or more {@code ConverterInfo} object. The {@code ConverterInfoReader} object
+ * is used to build a {@code Vector} of {@code ConverterInfo} objects from a
+ * jarfile.</p>
+ *
+ * <p>The {@code ConverterInfoMgr} manages the registry of {@code ConverterInfo}.
+ * It is a singleton class, so that only one registry manager will ever exist.
+ * It is the client program's responsibility to register {@code ConverterInfo}
+ * objects that correspond to the plug-ins that are to be used.</p>
+ *
+ * <h2>TODO/IDEAS list</h2>
+ * <ol>
+ * <li>The {@code ConverterInfo} object could contain
+ * {@code org.w3c.dom.Document} fragments that are accessed in a generic
+ * fashion rather than get/set methods for each item in the DTD. This would
+ * provide a more flexible approach, especially for adding custom tags to a
+ * specific Plug-in Configuration XML file (tags that are only used by its
+ * associated plug-in).</li>
+ * <li>{@code ConverterInfo} should allow the merge/serialize/deserialize logic
+ * to be included in separate plug-ins, if desired.</li>
+ * <li>{@code ConverterInfoMgr} could use the Java Activation Framework (JAF)
+ * to manage registration.</li>
+ * </ol>
