	21 .Sh DESCRIPTION
	22 The
	23 .Nm
	24 program generates a regular or random packing of grains, and outputs
	25 the grain data in
	26 .Xr granular 5
	27 format.
	28 .Pp
	29 The options are as follows:
	30 .Bl -tag -width Ds
	31 .It Fl D Ar max-diameter
	32 Specify maximum size of generated grains (default 1.0).
	33 .It Fl d Ar min-diameter
	34 Specify minimum size of generated grains (default 1.0).
	35 .It Fl h
	36 Show help text.
	37 .It Fl t
	38 Generate triangular packing (default: rectangular).
	39 .It Fl P
	40 Draw random diameters using a power-law distribution (default: uniform).
	41 .It Fl p Ar padding-factor
	42 Add padding between grains and add corresponding random variation
	43 to placement with the specified multiplier, respective to the grain
	44 radius (default 0.0).
	45 .It Fl X Ar x-offset
	46 Add the specified offset to all output x positions (default 0.0).
	47 .It Fl x Ar nx
	48 Generate
	49 .Ar nx
	50 grains in the x dimension (default 10).
	51 .It Fl Y Ar y-offset
	52 Add the specified offset to all output y positions (default 0.0).
	53 .It Fl y Ar ny
	54 Generate
	55 .Ar ny
	56 grains in the y dimension (default 10).
	57 .It Fl Z Ar x-offset
	58 Add the specified offset to all output z positions (default 0.0).
	59 .It Fl z Ar nz
	60 Generate
	61 .Ar nz
	62 grains in the z dimension (default 1).
