+Script debugging
+----------------
+
+Bash provides the ``set -x`` builtin command that "After expanding each simple command,
+for command, case command, select command, or arithmetic for command, display the
+expanded value of PS4, followed by the command and its expanded arguments or associated
+word list". This feature can be used to help debugging the `.pow` scripts and, together
+the ``--debug`` option in the server sub-command, the scripts executed in user requests.
