Maybe your mistaken. I believe the full version of Usgard is 1900 bytes
w/o a shell. With a comparable shell Usgard is greater than 2200 bytes
at least. Rigel which has all the features (plus lots more) of Usgard,
is going to be less than 1500 bytes. That's at least a good 700 bytes
less than Rigel (not to mention that you get fixed address relocation
and library support; two things not in Usgard). I can't argue that one
should use Rigel right now. But once I (and hopefully and lot more
people) develop games and the such for Rigel, I could make that
argument. Hey, power to Usgard, I hope it has a transitory success.
