## Introduction

This package provides the font ```\DblFont`'' (font `msbm10`), which corresponds to the so called blackdoard-bold symbols.

## The options

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).
