+# Purpose : coredesktop-dev try: run the working copy's code as if it were the
+#           deployed CoreDesktop, in a throwaway home with its own session

+Usage: coredesktop-dev try [--keep] [command...]
+
+Runs command (or a shell) with a throwaway HOME where
+~/.local/share/coredesktop is the working copy, and update, configure, version
+etc. in ~/.local/bin are the working copy's. It gets its own XDG_RUNTIME_DIR
+and D-Bus session, and no display, so it can't touch your desktop session.
+
+sudo, yay, pacman and systemctl still change this machine.
+
+  --keep   Keep the throwaway folder afterwards, and print where it is
+
+Example: coredesktop-dev try configure --list
+EOF

+TRY_COMMANDS=(update refresh sibling version configure audit)
