GNOME Core Applications are actually packaged in guix but have not been
included in guix's "gnome" package.
So I did [guix search "gnome-*"] and cross-checked the results with
guix's gnome package source (https://git.savannah.gnu.org/cgit/guix.git
found out that the following gnome core application packages are indeed
packaged in guix, but have not been included in guix's gnome package.
The following gnome core applications are also already packaged in guix
but requires correct renaming before adding to guix's gnome package?
rhythmbox --> gnome-music
shotwell --> gnome-photos
The following gnome core applications have already been included in
guix's gnome package but requires correct renaming?
epiphany --> gnome-web
envice --> gnome-documents
eog --> gnome-images
file-roller --> gnome-autoar
gedit --> gnome-text
nautilus --> gnome-files
I really hope if the above modifications are made, it will fulfill the
actual description of guix's gnome package (http://guix.gnu.org/package
