dh_desktop was a debhelper program that registers .desktop files.
However, it no longer does anything, and is now deprecated.
If a package ships desktop files, they just need to be installed in the
correct location (/usr/share/applications) and they will be registered
by the appropriate tools for the corresponding desktop environments.
This program is a part of debhelper.
