+Each command has a description (displayed on the button on the main page),
+and an actual command to execute. This command string can contain shell
+operators like |, &gt; and ; for executing multiple commands and pipelines.
+The string can also contain parameters like <tt>$foo</tt>, which are replaced
+by user inputs when the command is run. <p>
+
+These parameters can be entered into the table at the bottom of the page.
+For each parameter you must enter :
+<dl>
+<dt><b>Name</b>
+<dd>A unique code for this parameter. If the name is <tt>foo</tt>, then
+    <tt>$foo</tt> will be replaced by the parameter value when the command
+    is executed.<p>
+<dt><b>Description</b>
+<dd>The description next to this parameter on the main page.<p>
+<dt><b>Type</b>
+<dd>This option controls how the parameter is input. Available options are :
+	<ul>
+	<li><b>Text</b><br>
+	    A totally free-text input.
+	<li><b>User</b><br>
+	    A username from your system.

+	<li><b>Password</b><br>
+	    A totally free-text input, but with the password replaced by *'s.
+	<li><b>Menu</b><br>
+	    A drop-down menu of options, taken from the filename entered into

-   var_dump(\%hash_ref);     # HTML output (newlines and spaces replaced with <br> and &nbsp;)

+
+Each entry starts with:
+  ===== @ Tue Sep 21 12:00:00.123 2025 pid 1234 =====

+If the dump is also printed to the browser, it is HTML-escaped with preserved

+Long output is collapsed after the first 5 lines, with the rest shown inside an

+Returns 0 on success, or an "Error: ..." string. If Data::Dumper is missing,
