=head2 $c->debug
-Overload to enable debug messages (same as -Debug option).
+Returns 1 if debug mode is enabled, 0 otherwise.
-Note that this is a static method, not an accessor and should be overloaded
-by declaring "sub debug { 1 }" in your MyApp.pm, not by calling $c->debug(1).
+You can enable debug mode in several ways:
+(1) with the environment variables MYAPP_DEBUG, or CATALYST_DEBUG
+(2) the -Debug option in your MyApp.pm
+(3) by declaring "sub debug { 1 }" in your MyApp.pm.
+
+Calling $c->debug(1) has no effect.
