.TP
.B \-O M, \-\-maxcost=M
Controls compression of streamlines (default is 2e-7).
.TP
.B \-b x,.., \-\-box=x,y,..
Specify bounding box for streamline calculation.
.TP
.B \-j, \-\-closed
Outputs only closed streamlines.
.TP
.B \-p F, \-\-profile=F
Output list of values for coordinates defined in F.
.TP
.B \-o, \-\-mixed
Output text values in mixed cells only.
.TP
.B \-L L, \-\-level=L
