yacc: public domain?

[Tim Smith]

Isn't the operation of yaccpar described in various publicly accessable
documents?  Perhaps some kind yacc wizard could write a version, not
using any AT&T code, and place it in the public domain.  Then people
could use that if they are worried.

By the way, when is one "using" someone elses code?  For example, let us
say that I decided that I wanted to write a public domain yaccpar.  So
I look at /usr/lib/yaccpar to see how it interfaces to the rest of Eternia.
I read the code to see what it's supposed to do.  Then I write my own,
maybe even using algorithms gleaned (sp?) from /usr/lib/yaccpar.  Is my
new yaccpar then mine or AT&Ts?
