+# Basic idea: eselect manages a gschema override file located in
+# /etc/eselect/gnome-shell-extensions/ that overrides GNOME Shell's
+# 'disabled-extensions' or 'enabled-extensions' (depending on
+# current shell version) GSettings key; the override file is
+# symlinked from /usr/share/glib-2.0/schemas/
