pre-computing tiles & mod_tiles's render_list behavior

As I understand it, if one want to pre-compute all of the various tiles, the render_list program could be used by doing the following:

render_list --all 

Or, is there a better way?

Just to test it, I created a file called tile_list.txt which contains only:

0 0 1

and then executed the command:

cat tile_list.txt | render_list -v

The output contains:

got: x(0) y(0) z(1)
Waiting for rendering threads to finish

The program never exits and no other output appears.

I cannot tell if this is the expected behavior or if something is wrong.

Nevermind…I realized that I needed to use the --map flag to specify ajt which is the default map name used in the tutorial.
