Thierry,

Thanks for more excellent work on KerTeX. I don't use LaTeX myself, just
good old plain TeX, but I always turn to KerTeX for that.

There does seem to be some minor permissions issues on downloads.kergis.com
at the moment, affecting get_mk_install.sh, kertex_bundle.tar, and possibly
other files. Those two at least consistently return `403 Forbidden'.

The individual source tarballs don't seem to affected.


Thanks again for all the hard work,

-- Byron Grobe
