Do you mean setting it as a default application for mailto links eg in
your browser?
This is part of the MIME specification[0] and should be an option for an
installer script/package, otherwise users can do it on their own.
Shipping a .desktop file in the repo would make this easier.
The MIME type for mailto links should be `x-scheme-handler/mailto`
though I haven't found it in any specification yet.
