//
// htfuzzy: Create one or more ``fuzzy'' indexes into the main word database.
// These indexes can be used by htsearch to perform a search that uses
// other algorithms than exact word match.
//
// This program is meant to be run after htmerge has created the word
// database.
//
// For each fuzzy algorithm, there will be a separate database. Each
// database is simply a mapping from the fuzzy key to a list of words
// in the main word database.
