 \textsc{Font Table for BBOLDX-Regular}:\\

 \newpage
-This package creates two basic commands, \verb|\bbxfamily| and \verb|\bbbxfamily| to identify the fonts that should be considered regular and bold, and uses them to define  macros \verb|\textbb| and \verb|\textbfbb| by which you may access any character, though not necessarily by convenient means as the fonts do not completely follow any standard encoding. Nonetheless, it does understand Roman letters and digits, as well as some punctuation and symbols: e.g., \verb|\textbb{(A)b[1].,!?<>-}| renders as \textbb{(A)b[1].,!?<>-}. Characters may also be accessed by consulting the above table for the position of the character. For example, lowercase psi is in slot 32 decimal={"20} (HEX), so \verb|\textbb{\char32}| or \verb|\textbb{\char"20}| yields \textbb{\char"20}. It also creates macros \verb|\mathbb|, \verb|\mathbfbb| that are specific to math mode but are more limited in scope but work as expected for all Roman alphabetic arguments.

-There are no special macros for digits because they are easily handled with \verb|\textbb{0}| through \verb|\textbb{9}| and \verb|\textbfbb{0}| through \verb|\textbfbb{9}|. (In this mode, \verb|\mathbb| and \verb|\mathbfbb| don't work as expected with numeric arguments.)

+Corrected some errors in the sty file so that \mathbb and \mathbfbb are now handled correctly in the default case.
 
 Changes in version 1.03
 1. New options, including one to force handling as a Symbol Font rather than as a Math Alphabet.
