Dear maintainer,

I see that the package debichem-analytical-biochemistry (version 0.0.12)
suggests mmass which is not in unstable.

This can be seen in
https://packages.debian.org/unstable/debichem-analytical-biochemistry .
Search for "Package not available".

The missing package used to be in Debian but they were removed some time
ago:

- https://tracker.debian.org/pkg/mmass

Should it be dropped or changed?

Thank you,
