I was meaning to put together hyperlink *and* cross reference, which is
achieved in the recent versions of eplain with the \definexref and \ref or
\refn commands, but only (as far as I know) within a single file.

The commands you reported above cannot, if I understand well, play the role of
cross referencies: e.g., let me read in a start point that something has
changed in the destination point (paragraph number or so).  If I'm wrong,
please would you correct me.

To do what I want I had to put old eplain cross references commands `inside'
hyperbasics.tex commands and vice versa, and besides to make all the .aux files
readable from every file.

Thanks, cheers,
Rodolfo
