The tuxpaint package needs one of these Tamil fonts (in particular, TSCu_Comic) for the newly committed to tuxpaint CVS Tamil support. I would be very interested to test ttf-tamil-fonts (or ttf-indic -- whichever is eventually going to go into sid and includes the font I need) so I can prepare to modify my package to make use of it.
Thanks, Ben Armstrong, Debian tuxpaint maintainer
