+ * A {@code Multimap} that cannot hold duplicate key-value pairs. Adding a
+ * key-value pair that's already in the multimap has no effect. See the {@link
+ * Multimap} documentation for information common to all multimaps.
+ *
+ * <p>The {@link #get}, {@link #removeAll}, and {@link #replaceValues} methods
+ * each return a {@link Set} of values, while {@link #entries} returns a {@code
+ * Set} of map entries. Though the method signature doesn't say so explicitly,
+ * the map returned by {@link #asMap} has {@code Set} values.
+ *
+ * <p>If the values corresponding to a single key should be ordered according to
+ * a {@link java.util.Comparator} (or the natural order), see the
+ * {@link SortedSetMultimap} subinterface.
+ *
+ * <p>See the Guava User Guide article on <a href=
+ * "http://code.google.com/p/guava-libraries/wiki/NewCollectionTypesExplained#Multimap">
