  -i, --add-missing-danish
                        Add special Danish characters. Needed for proper

  -c CREATOR, --creator CREATOR

  -v VERSION, --version VERSION
                        Sets font version number

NOTE:
Both -l and -u are listed as "optional arguments", but obviously at least one
of them has to be specified.

Example
-------
Usable files can be found in the "Character Sets"-section at this page (which
is not mine by the way):
http://kofler.dot.at/c64/

Given the input files c64_lower.64c and c64_upper.64c:

./c64ttf.py -l c64_lower.64c -u c64_upper.64c -o c64.ttf -m -a \
-n "Commodore 64" -y 1982 -c Commodore -v "1.00"

This will create a font called "Commodore 64" with all lowercase, uppercase,
and graphics characters included. Additionally, the missing ASCII characters
are included as well.
