What 'step 2.' are you talking about?  Did I miss something?

Are you talking about the same thing as to which I was refering, when
I wrote, in Message-ID: <20010622225624.C30096 at gelfand.mdcc.cx>

?  Could you please tell what exactly your plans are?  We might get
synergy.

You are talking about the need for a complete turing-machine-like language
to build queries for the dlf files?  I believe the suggestion which has
been made to introduce a simplified language, but next to that still
keep it possible to interface with fullblown perl or shell, is valuable.
If the drawbacks of such a possibility are not too bad, we surely should
enable this.

Bye,
