Announcement text: ---------------------------------------------------------------------- dozenal is a package for typesetting documents in base twelve, also called dozenal. It includes a macro by David Kastrup for converting positive whole numbers to dozenal from decimal (base ten). It also includes a few other macros, redefines all the standard counters to produce dozenal output, and provides Metafont characters, in Roman, italic, slanted, and boldface versions of each, for ten and eleven (the Pitman characters preferred by the Dozenal Society of Great Britain). These characters were designed to blend well with the Computer Modern fonts. ----------------------------------------------------------------------
