 Description: Implements an approximate string matching version of R's native
- 'match' function. Can calculate various string distances based on edits
+ 'match' function. Also offers fuzzy text search based on various string
+ distance measures. Can calculate various string distances based on edits
  (Damerau-Levenshtein, Hamming, Levenshtein, optimal sting alignment), qgrams (q-
  gram, cosine, jaccard distance) or heuristic metrics (Jaro, Jaro-Winkler). An
  implementation of soundex is provided as well. Distances can be computed between
