Trie is a kind of digital search tree, an efficient indexing method with o(1) time complexity for searching. comparably as efficient as hashing, trie also provides flexibility on incremental matching and key spelling manipulation. this makes it ideal for lexical analyzers, as well as spelling dictionaries.

this library is an implementation of double-array structure for representing trie, as proposed by junichi aoe. the details of the implementation can be found at http://linux.thai.net/~thep/datrie/datrie.html

this package contains the program files which is used with the library, including trietool, the trie manipulation tool.
