Glad to hear it's useful. I can probably scrounge up others or make
some more if there is interest.
BTW, the version on the trunk shows errors on my system:
1. The env top line works with Python but not with perl (but it
doesn't matter if it's executed as "perl metaballs.pl"--not usually
done on Linux).
2. The HERE tokens must be at the beginning of the line (unless more
tricks are used).
Here is a patch that works for me:
<begin-patch>
