Most of them are +commands for positioning and text writing. These commands are tolerant +of whitespace. Optionally, syntactical space can be inserted before, +after, and between the command letter and its arguments. All of these +commands are stackable; i.e., they can be preceded by other simple +commands or followed by arbitrary other commands on the same line.
