 The %include option can be used recursively.
 New configuration files or directories cannot be added to already running Tor
 instance if **Sandbox** is enabled.
 
+The supported wildcards are * meaning any number of characters including none
+and ? meaning exactly one character. These characters can be escaped by preceding
+them with a backslash, except on Windows. Files starting with a dot are not matched
+when expanding wildcards unless the starting dot is explicitly in the pattern, except

 By default, an option on the command line overrides an option found in the
 configuration file, and an option in a configuration file overrides one in
 the defaults file.
