Never mind---I have been distracted by other things recently, and
now I am back to work on this, so your reply is in fact just in time,
thanks :)

Good, insert-format-handler will suffice my needs I think.
Dumb question follows: what is the best place to call
insert-format-handler from?

To be more specific about my goals:
I have a Racket installation, and I would like to have this
format handler registered by the moment a user starts DrRacket
and opens some file in it.

I tried and hijacked
to insert my (handler:insert-format-handler) to it, but
this surely does not seem to be a good solution.

My spreadsheet-editing module is currently in a collection
that is "raco link"-ed to the Racket installation. Is there
a way to call (handler:insert-format-handler) from a collection
module before the collection is (require)-d? Or can I form
a package from my collection and use some package mechanism
for that?

Also, a related question: what would you recommend for
adding a certain file type to the DrRacket's file->open
dialog, where currently are "Racket Sources" and "Any"?
