Is 3.0b the latest available OpenToken version?
I'am not so sure, because some of the examples don't compile
using gnat 4.0.3 (Debian 4.0.2-4).
Here is my problem : I am implementing a recursive descent parser, and
my grammar contains optionnals keywords, that will be ignored.
Here is an exemple:
- do this and this
- do this and also this
"also" is an optionnal keyword.
I am wondering what is the best way to deal with this.
What comes to my mind is to create a selection (In OpenToken parlance)
between the keyword "also" and a null token, child of the abstract
"Recognizer.Nothing" token.
It seems far to complex to be the right way. Any hints?

PS : and once more question : is there still a mail list for OpenToken
on AdaPower site? (I would like to have a look at the archive)
