	This device-independent color name database is provided just as an exa\
	mple.
	There are no claims that these color specifications are or should be b\
	ound
	to the corresponding color name.
	
	As you can see, the start of the database is indicated by "XCMS_COLORD\
	B_START".
	Anything before this is assumed to be comments.  The "0.1" indicates t\
	he
	version number of the format/syntax used in this file.  The color name\
	 is
	delimited from the color specification by one or more tabs.
