4/// Draw the Greek letters as a table and save the result as GIF, PS, PDF
5/// and SVG files.
6/// Lowercase Greek letters are obtained by adding a # to the name of the letter.
7/// For an uppercase Greek letter, just capitalize the first letter of the
8/// command name. Some letter have two representations. The name of the
9/// second one (the "variation") starts with "var".
