  # NAME
  
  Text::Sift4 - A Perl 6 Sift4 (Super Fast and Accurate string distance algorithm) implementation
  
  # SYNOPSIS
  
  ```
  use Text::Sift4;
  
  say sift4("abc", "ab");  # OUTPUT: «1␤»
  say sift4("ab", "abc");  # OUTPUT: «1␤»
  say sift4("abc", "xxx"); # OUTPUT: «3␤»
  
  ```
  
  # DESCRIPTION
  
  Text::Sift4 is a Perl 6 Sift4 implementation. Sift4 computes approximate results of Levenshtein Distance.
  
  # METHODS
  
  ## sift4
  
  Defined as:
  
  ```
  sub sift4(Str $lhs, Str $rhs, Int :$max-offset = 5 --> Int:D) is export
  
  ```
  
  returns approximation of Levenshtein Distance.
  
  * Str `$lhs` is one side of the strings to compare.
  * Str `$rhs` is one side of the strings to compare.
  * Int `:$max-offset` is the maximum offset value. The value is default to 5.
