mathbbol.rme Readme File for the mathbbol package by J"org Knappen (c) Copyleft 1995--1999 J"org Knappen under the GNU licence version 2 The mathbbol package exploits the bbold-fonts and the stmaryrd-fonts designed by Alan Jeffrey and Jeremy Gibbons. 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 letters, greek letters 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Version 2 of the package, the extensions are taken from the stmaryrd fonts instead of cspex, since the latter fonts are withdrawn by their author.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. All upper and lowercase latin letters are accessible this way. It overwrites AMS-LaTeX's \mathbb (and can be overwritten if you load amsfonts after mathbbol) o \mathbb{0} to produce the blackbord bold digit 0. All digits are accessible this way o \mathbb{\Lambda} to produce a blackbord bold Lambda. All uppercase greek letters are accessible this way. 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. There are more symbols in the font, which aren't defined, because they are never (really?) needed. 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. This package contains 4 files, namely mathbbol.rme This readme file mathbbol.sty The package file ubbold.fd Font definition file for the bbold fonts ustmary.fd Font definition file for the stmaryrd fonts Conflicts with other packages: If amsfonts is loaded together with mathbbol, the later package decides the shape of the \mathbb letters. If amsmath is loaded, \mathbb{} does not work any more. To work around, save the original definitions of \Gamma etc. before loading amsmath and restore them afterwards: \let\savedGamma\Gamma \usepackage{amsmath} \let\Gamma\savedGamma J"org Knappen, Barbarossaring 43, D-55118 Mainz, Allemagne Author of the Book: Schnell ans Ziel mit LaTeX2e, Oldenbourg-Verlag M"unchen, 1997, ISBN 3-486-24199-0. /mathbbol.rme
