mathbbol.rme Readme File for the mathbbol package by J"org Knappen (c) Copyleft 1995, 1996 J"org Knappen under the GNU licence version 2 The mathbbol package exploits the bbold-fonts and the cspex-fonts designed by Alan Jeffrey. Many people prefer these fonts over the AMS \mathbb, because the symbols for the real numbers, complex numbers, etc. look just right. But the Jeffrey fonts contain more: blackbord bold digits, lower case, greek and even punctuation. To use this package, just write \usepackage[cspex,bbgreekl]{mathbbol} in the preamble of the document. Note that this package has two options. -- cspex activates the special extension font, allowing you to say $\left\Lbrack ... \right\Rbrack$ to get double lined extensible brackets. With Version 2 of the package, the extensions are taken from the stmaryrd fonts instead of cspex, since the latter fonts are withdrawn by their author. -- bbgreekl activates commands for the lower case blackbord bold greek, which are just \bbalpha ... \bbomega. Without options, the following commands are defined: o \mathbb{A} to produce blackbord bold A. It overwrites AMS-LaTeX's \mathbb (and can be overwritten if you load amsfonts after mathbbol) o \Langle, \Lbrack, \Lparen to produce blackbord bold <, [, ( o \Rangle, \Rbrack, \Rparen right counterparts of the above o \Eins to produce blackbord bold digit 1. Please find the bbold and stmary fonts on your nearest CTAN archive in directory tex-archive/fonts/bbold. This package assumes that the Sauter-tools, to be found in tex-archive/fonts/cm/sauter, are used to generate the fonts at true sizes.
