+*include* ['FILENAME'...]::
+
+ Read the named files and act as if their contents stood in
+ place of the *include* stanza. A 'FILENAME' may be a glob
+ pattern, in which case all matching files are used, sorted by
+ their filenames. If a 'FILENAME' is a relative path, it is
+ treated relative to the directory containing the file from
+ which the *include* stanza was read, even if the inclusion has
+ been nested. Inclusions may be nested to any level.
