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