    00004  * Project:  Common Portability Library
    00005  * Purpose:  Implementation of CPLKeywordParser - a class for parsing
    00006  *           the keyword format used for files like QuickBird .RPB files.
    00007  *           This is a slight variation on the NASAKeywordParser used for
    00008  *           the PDS/ISIS2/ISIS3 formats.
