+# (files/dirs/etc...).  The -a and -o flags control the requirements
+# of the paths.  They correspond to "and" and "or" logic.  So the -a
+# flag means all the paths must exist while the -o flag means at least
+# one of the paths must exist.  The default behavior is "and".  If no
+# paths are specified, then the return value is "false".
