+"""Run a selected shell command in a terminal.

+The classifier tags shell-command-looking selections as
+``ContentType.COMMAND`` (e.g. ``wpctl set-volume @DEFAULT_AUDIO_SINK@ 50%``),
+but nothing acted on them - this plugin adds the missing "Run in terminal"
+button for exactly that content type.
+
+The heavy lifting lives in ``actions.run_in_terminal``: it finds an available
+terminal emulator, optionally shows a confirmation dialog
+(``terminal_confirm_run``, default on), echoes the command, runs it, and keeps
+the terminal open afterwards (``terminal_keep_open``, default on). Launch is
+done with a real argv list (never ``shell=True`` at construction), and the
+confirmation dialog is the guard against running a malicious-looking selection
+by accident.
