      dawgdic provides a library for building and accessing

      dictionaries implemented with directed acyclic word graphs

      (DAWG). A dawg is constructed by minimizing a trie as a

      deterministic finite automaton (DFA), and thus the dawg has

      an advantage in memory usage. In addition, dawgdic uses a

      double-array as a base data structure, so its retrieval

      speed is as fast as that of Darts, a library for building

      and accessing double-array tries.
