Nautilus depends on thumbnail source code files from the gnome-desktop project. Therefore, when the upstream https://gitlab.gnome.org/GNOME/gnome-desktop project releases a new version of the files, they should be downloaded and merged into the nautilus project.
The script downloads the latest gnome-desktop project files to the developer's local nautilus source folder so that the developer can commit the updated files to the nautilus project.
Fixes: #839
Since it’s 2017 already, Nautilus should use a build system that doesn’t
take longer to set up the build than it takes to actually build. An
observed build time using Ninja of roughly one-fifth of what it took
Autotools is more than reason enough to add support for Meson. Along
with that, this commit adds a convenience script to generate a tarball
for releases, since we use libgd as a submodule and Meson does not
handle source distributions.
