I've written tools for my own use which approximately this:

http://git.nix.is/?p=avar/tah-avar;a=tree;h=master;hb=master

I use it like this, to render stuff in the city I'm editing I just changed:

time (lwp-request
'http://api.openstreetmap.org/api/0.5/map?bbox=-22.13,63.993,-21.617,64.26'
| perl ../script/osm-to-tilenumbers.pl --zoom 12 --predicate
'abs($sec_ago) < (60**2 * 1)' | perl ../script/tilesGen-monitored.pl
--zoom 12)

Or, to generate a list of tiles:

time (perl -E 'say for map { my ($x,$y) = $_ =~ /(\d+)\D+(\d+)/;
"$x,$y" } @ARGV' 1888/1063/ 1889/1063/ 1888/1064/ 1889/1064/ | perl
../script/tilesGen-monitored.pl --zoom 12)
