import org.gvsig.gpe.parser.GPEParser;

 * This class is used to add properties that can be used

 * by the GPE parsers and writers.

 * <p>

 * It is not possible for the consumer application to have any

 * dependence with a concrete parser or writer. But sometimes it

 * is necessary to establish some configuration parameters

 * (principally to write). This class provides a mechanism to

 * set all these parameters using the SPI (Service Provider Interface) 

 * mechanism  

 * </p>

 * <h2>Implementation Lookup</h2>

 * <p>

 * The SPI provides a mechanism to register a set of properties that

 * both the parsers and the writers need to work. Every parser (or writer)

 * is the responsible to create a set of parameters and register them

 * in this class

 * </p>

 * <p> 

 * To register a set of properties a file named <code>org.gvsig.gpe.IGPEProperties</code>

 * shall exist in the class path in the implementation's <code>META-INF/services</code> folder.

 * </p>

 * <p>

 * The content of the files for a given implementation consists of full qualified 

 * class names, one per line. For example, an hypotetical <code>MyParserProperties</code> 

 * in the package <code>org.gvsi.gpe.format</code> and bundled in a jar file 

 * called <code>org.gvsig.gpe.format.jar</code> shall provide the following 

 * resources:

 *  

 * <pre>

 * <code>

 * $jar tvf org.gvsi.gpe.format.jar

 * META-INF/services/org.gvsig.gpe.IGPEProperties

 * org/gvsig/gpe/MyParserProperties.class

 * </code>

 * </pre>

 * 

 * And the content of the file <code>META-INF/services/org.gvsig.gpe.IGPEProperties</code> 

 * shall be a single line of text with the <code>org.gpe.gpe.format</code> class name.

 *
