# Installs files into the system
#
# All six of upstream's, at upstream's paths, plus this fork's two. HyprCosmic
# is a fork of COSMIC rather than something installed next to it, so a machine
# that installs this gets its cosmic-session from here and there is nothing else
# on disk to provide the target, the mimeapps list or the dconf profile.
#
# The two extra files are what make it a HyprCosmic install rather than a rebuilt
# COSMIC one:
#
#   data/start-hyprcosmic  -> /usr/bin/start-hyprcosmic
#   data/hyprcosmic.desktop -> a second entry on the greeter's menu
#
# Both session entries are installed, and both are served by these same
# binaries. That is deliberate. Replacing COSMIC does not have to mean removing
# its shell, and keeping cosmic.desktop costs one file while preserving the one
# property worth keeping from the old beside-install layout: if the HyDE shell
# will not start, there is still something on the greeter's menu that will.

    # prefix into it would break that. The script says so where it searches.
