+     "The package supports typesetting documents whose counters are
+represented in base twelve, also called @dfn{dozenal}.  It includes a macro
+for converting positive whole numbers to dozenal from decimal (base ten)
+representation.  The package also includes a few other macros and redefines
+all the standard counters to produce dozenal output.  Fonts, in Roman, italic,
+slanted, and boldface versions, provide ten and eleven.  The fonts were
+designed to blend well with the Computer Modern fonts, and are available both
+as Metafont source and in Adobe Type 1 format.")
