     *	    Returns the basic information about this plugin. Including:
     *
     *	    bMultipleLoad	Whether or not this plugin can be instantiated
     *				multiple times. All File Formats must set
     *				this value to TRUE.  The only other type of
     *				plugin that can specify bMultipleLoad=TRUE is
     *				a filesystem plugin.  Any plugin that sets
     *				this flag to TRUE must not use global variables
     *				of any type.
     *
     *				Setting this flag to TRUE implies that you
     *				accept that your plugin may be instantiated
     *				multiple times (possibly in different
     *				address spaces).  Plugins are instantiated
     *				multiple times only in the server (for
     *				performance reasons).
     *
     *				An example of a plugin, that must set this
     *				flag to FALSE is a filesystem plugin that 
     *				uses a single TCP connection to communicate
     *				with a database.
