xistercian allows you to use Cistercian numerals in LaTeX. The
glyphs are created using PGF and to a certain degree
configurable. You can use Cistercian numerals as page numbers
using \pagenumbering{cistercian}. The two main macros are:
\cistercian{<counter>} formats the LaTeX2e counter as a
Cistercian numeral \cisterciannum{<integer>} formats the
integer (given as a string) as a Cistercian numeral
