Dear maintainer(s),

I noticed that package debichem-visualisation recommends gabedit, gamgi,
gdis and viewmol, which are currently not available in unstable.

See:

- https://tracker.debian.org/pkg/gabedit
- https://tracker.debian.org/pkg/gamgi
- https://tracker.debian.org/pkg/gdis
- https://tracker.debian.org/pkg/viewmol

For details on when it was deleted, bug number, etc.

Note that #1134237 (for package
debichem-input-generation-output-processing) recommended also gabedit
and viewmol. Perhaps the same alternatives should be used here. Sadly, I
am not familiar with the ecosystem of that packages to suggest an
alternative.

Would it make sense to remove or update they?

According to Debian Policy §2.2.1, packages in main should only
recommend packages available in main (except for non-default
alternatives):

Thank you for your time,
