+@findex exclude-tag
+Another option, @option{--exclude-tag}, provides a generalization of
+this concept. It takes a single argument, a file name to look for.
+Any directory that contains this file will be excluded from the dump.
+
+@table @option
+@opindex exclude-tag
+@item --exclude-tag=@var{file}
+Causes @command{tar} to ignore directories containing @var{file}.
+Multiple @option{--exclude-tag} options can be given.

+dir/
+dir/blues
+dir/jazz
+./tar: dir/folk/: contains a cache directory tag tagfile; not dumped
+$ @kbd{tar -tf archive.tar}
+dir/
+dir/blues
