 * </p>

 * <p>

 * To register a GPEParser implememntation, a file named <code>org.gvsig.gpe.parser.GPEParser</code>

 * shall exist in the class path (hence the ability to have multiple files equally namded budled in

 * different jar files), in the implementation's <code>META-INF/services</code> folder.
