It seems best to concentrate on releasing 1.29. As for the semantic parser,
it appears to be no hurry taking it out, other than it may be cumbersome at
some point keeping it if new algorithms are added to Bison. But also, there
seems to be no point in keeping it either: If one is interested in this
semantic stuff, it seems better to concentrate on the more recent research.

I checked with Corbett if his thesis was available in TeX/DVI format, and
said it was on some old tape he didn't know if it still was readable.
