# Each block:
# 1. Pull in polkit-0.101 for pretty authorization dialogs
# 2. Introspection stuff needed via imports.gi.*
# 3. gnome-session is needed for gnome-session-quit
# 4. Control shell settings
# 5. Systemd needed for suspending support
# 6. xdg-utils needed for xdg-open, used by extension tool
# 7. gnome-icon-theme-symbolic and dejavu font neeed for various icons & arrows
