How the state of the turtle changes:
"F" Move forward a step of length d. The state of the turtle
changes to (x, y, α), where x = x + d*cosα and y = y + d*sinα.
A line segment between points (x, y) and (x, y)is drawn.
"f" Move forward a step of length d without drawing a line.
"+" Turn left by angle δ. The next state of the turtle is
(x, y, α+δ). The positive orientation of angles is counterclockwise.
"-" Turn right by angle δ. The next state of the turtle is (x, y, α-δ).
"&" Pitch down by angle δ.
"∧" Pitch up by angle δ.
"\" Roll left by angle δ.
"/" Roll right by angle δ.
"|" Turn around using (-x, -y, z) on global or (-x, y, z) on local.
"[" Push the current state of the turtle onto a pushdown
stack. The information saved on the stack contains the
turtle’s position and orientation, and possibly other attributes such as the color and width
of lines being drawn.
"]" Pop a state from the stack and make it the current state
of the turtle. No line is drawn, although in general the
position of the turtle changes
"{" Indicates the beginning of a leaf (6-sided polygon) whose boundary is formed
from the edges enclosed between the curly braces.
"}" Indicates the completion of a leaf.
"'" Increments the color index by 1.
"!" Decrements the diameter of line segments.
