+complexity=COMPLEXITY
+
+    Sets the complexity (expertise) level of Tux Paint, which can either
+    disable some Magic tools, or cause them to operate differently. (For
+    example, the "Clone" tool is not available in novice mode, and the 1-, 2-,
+    and 3-point perspective tools do not allow vanishing points to be edited in
+    beginner mode.)
+
+    The COMPLEXITY value may be one of:
+
+    advanced (the default)
+        "Advanced" — For users familiar with Tux Paint and who can operate more
+        complex tools.
+
+    beginner
+        "Beginner" — For users comfortable with Tux Paint, but where complex
+        tools may cause confusion or frustration.
+
+    novice
+        "Novice" — For first-time Tux Paint users, users inexperienced with
+        computers, or those with special accessibility needs.
+
+
+    📜 Note: The complexity option was added to Tux Paint in version 0.9.32.
+    Consult the individual Magic tools' documentation.
+
+    ⚙ Note: If used in a system-wide configuration file, may be overridden by
+    the user's configuration file using "complexity=advanced". In both cases,
+    may be overridden by the command-line option "--complexity=advanced".
