Roman
Roman converts numbers form their Roman form to their arabic form and vice versa
Roman was originally written by OZAWA Sakuro. I updated it to add proper Makefile and tests in version 1.2, and support for numbers above 4000 in version 1.3 (requires Unicode support).
Get Roman-1.2.tar.gz (no unicode support required),
Get Roman-1.3.tar.gz (uses unicode characters for numbers above 4000),
