+Maximum number of tags in an expression. A query with many ANDs and

+too slow, as well as providing some eventual limit when processes
+recurse into the filesystem. The default is 10.

-=head1 EXAMPLES
-
-To mount an id3fs filesystem which indexes B<~/music/albums> on
-B<~/music/tags>:
-
-First create the index:
-
-    id3fs-index -v ~/music/albums
-
-If you have a large collection of music, this may take some time.
-
-Then create the mountpoint:
-
-    mkdir ~/music/tags
-
-and mount the filesystem:
-
-    id3fsd ~/music/albums ~/music/tags
-
-Then explore the tags in ~/music/tags/
