and behavioral twiddling, but I don't know what.

	tran/
biquad.alg	general (time-invariant) second-order filter.
fmosc.alg	modified to tolerate 0 for carrier Hz.

	runtime/
eub.lsp		new functions.  into dspprims.lsp?
eubutil.lsp	take what you like, but at least what eub.lsp needs.

	doc/
eub.html	docs for fns in eub.lsp
