Dear Maintainer,

The Debian package, via debian/control, can declare where the package is
maintained, for example Vcs-Git and Vcs-Browser for this package should
indicate that it is maintained on salsa. It's nice to do this so that people
can help out, find the most recent versions etc.

https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-vcs-fields

https://wiki.debian.org/Salsa/Doc#Canonical_URLs

(it's also unusual for the VCS on salsa to have a different name to the source
package itself: debian-crossgrader vs debian-crossgrading)

Thanks for maintaining this interesting package!

regards
Stuart
