: The options are as follows:

: .Bl -tag -width "-l length"

: .It Fl d Ar delay

: Specifies a delay, in milliseconds, between each update.

: This is useful for fast terminals.

: Reasonable values are around 20\(en200.

: The default is based on the terminal speed.

: If the terminal is 9600 baud or slower no delay is used.

: Otherwise, the delay is computed via the following formula:

: .Pp

: .Dl delay = speed / 9600 \- 1

: .It Fl f

: Makes a

: .Dq field

: for the worm(s) to eat.

: .It Fl l Ar length

: Specifies a length for each worm; the default is 16.

: .It Fl n Ar number

: Specifies the number of worms; the default is 3.
