See the r.in.xyz help page for general parameter usage and tips.
The map is created using the rows, columns, and depths set by current region settings. Be sure to check and adjust these with the g.region module before performing the import.
Unlike r.in.xyz, reading from stdin and z-scaling are not possible.
To enable parallel processing support, set the workers= option to match the number of CPUs or CPU-cores avaiable on your system.
Points falling exactly on a vertical bound will belong to the depth band below them, except for points exactly on the top bound, which will belong to the top-most slice.
The script is expected to be nearly as efficient as if it was fully written in C.
