 * Project:  Common Portability Library

 * Purpose:  Implementation of CPLKeywordParser - a class for parsing

 *           the keyword format used for files like QuickBird .RPB files.

 *           This is a slight variation on the NASAKeywordParser used for

 *           the PDS/ISIS2/ISIS3 formats.
