I have a question about the interface. It uses the shell now, it seems. (I
could be wrong). The guile system call has a (system cmd ) which uses the shell
and a system* call which takes (system* cmd arg ...) So that it does not rely
on the shell. Maybe a similar interface could be useful (and more secure) for
the pipeline as well.
Thank you for this patch.
