This package provides the font ``\DblFont'' (font msbm10), which corresponds to the so called blackdoard-bold symbols.
  For each uppercase letter ``X'' a corresponding ``X''
  and ``XX'' options exist: they declare the commands
  ``\X'' and ``\XX'' respectively, which both generate
  the letter X in DblFont.
  
  If a command named ``\X'' or ``\XX'' already exists in
  LaTeX, its definition is first saved in ``\BackDoubleX'' or
  ``\BackDoubleXX'' respectively.
Also a ``RT'' option exists: it declares the ``\RT'' command, which generates the two letters RT in DblFont (useful for the Raviart-Thomas spaces).
