I have re-arranged the startup so this is now possible. To make the transition I can arrange that the command line is not processed in C but passed to scheme depending on the name used to invoke denemo. Or ...???

I wonder if we should hand the whole of the command line processing over to scheme?
I am not exactly sure how it would work, but, roughly, denemo starts initializes scheme runs a procedure (defined in denemo.scm) with the command line as the parameter.
That procedure calls prints out the help and exits or calls d-Open etc, etc....

Denemo does know a certain amount of command line arguments like version, help or a file.

It would be great if we had

a) a commandline argument for scheme variables like --scheme abc def geh --other arg


b) forward all unknown --argument

to a top-level scheme variable cmdarg_[name] which is just #t from there on. It does no harm but can be useful:

This would be a way to trigger certain behaviour for Denemo, most obvious setting parameters for Denemos GUI or other options.

Or we could use it for something like --verbose to enable debug output for scripts, which would have to do:
(if cmdarg_verbose (display "xy"))
