Description:
RFC 2229 compliant modular dictionary server (WordNet module)
GNU Dico is an implementation of the DICT protocol as defined in RFC 2229. It is fully modular: the daemon itself (dicod) provides only the server functionality, and knows nothing about database formats. Actual searches are performed by functions supplied in loadable modules. A single module can serve one or more databases. . This package provides an abstract layer for reading WordNet lexical database files.
