+Changes in version 1.03
+1. Added options symbols (load as symbol font, not as MathAlphabet), bfbb (force \mathbb to refer to bold weight.)
+2. Added math macros for Greek letters if loading as symbol font, and text macros for those characters if in MathAlphabet mode.
 
 Changes in version 1.02
 1. Added  Greek uppercase letters (regular weight only.)

-DSSerif is short for Double Struck Serif, and, while based on the Courier  clone of URW++ (version 2), though much distorted, its double striking and weights are very much in the style of the STIX double struck fonts.

+DSSerif is short for Double Struck Serif, and, while based on the Courier  clone of URW++ (version 2), though much distorted, its double striking and weights are very much in the style of the STIX double struck fonts.

+{\tt bbsymbols} (or {\tt symbols}) controls whether the  font is set up as a symbol font. (The default is to set it up as a Math Alphabet, which makes more efficient use of the LaTeX limitation to just 16 math families.)
+\item {\tt bfbb} forces the package to not load the regular weight, but use \verb|\mathbb| as if bold were the regular weight.
