Configuration options can be imported from files or folders using the %include
option with the value being a path. If the path is a file, the options from the
option with the value being a path. This path can have wildcards. Wildcards are
expanded first, using lexical order. Then, for each matching file or folder, the
following rules are followed: if the path is a file, the options from the
file will be parsed as if they were written where the %include option is. If
the path is a folder, all files on that folder will be parsed following lexical
order. Files starting with a dot are ignored. Files on subfolders are ignored.
order. Files starting with a dot are ignored. Files in subfolders are ignored.
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
on Windows.
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.
