This is a (hopefully) working version of the bison program distributed
on disk 4. Bison is a clone of the UNIX YACC program (a parser generator).

There are probably (read: for sure) some bugs left in the code, but my
overall impression is that the code is good and that bison works. This
version handles both example A and C in Stephen Johnsons YACC manual.

If you find any bugs or have some ideas about improvements you can either:
	Write and tell me.
Or better:
	Fix it yourself and distribute the improved version.

YACC is described in a nice article in volume 2 of the UNIX manual.
The article contains working examples.

I have used Lattice 3.10. I do not have a Manx compiler so bison is not
Manxified.
