Usage:
hcurve [OPTION..] ORDER
Options:
--help         | -h   displays this message
--ascii        | -a   visualizes the curve in form of ascii art
--color        | -c   visualizes the curve in form of ppm
--grey         | -g   visualizes the curve in form of pgm
--instructions | -i   outputs "instructions" for building the curve (F - move forward, + - rotate right by 90 degrees, - - rotate left by 90 degrees)
--rainbow      | -r   the color (if used with -c) or the brightness (if used with -g) of the curve changes depending on the length of the curve
--zero         | -z   sets padding to 0 and weight to 1
--weight=X            sets width of the curve to X
--padding=X           sets padding to X
--background=X        fills the background with X
