libagrep-ocaml-dev 1.0-12build1 (arm64 binary) in ubuntu bionic

 This OCaml library implements the Wu-Manber algorithm for string searching
 with errors, popularized by the "agrep" Unix command and the "glimpse" file
 indexing tool. It was developed as part of a search engine for a largish MP3
 collection; the "with error" searching comes handy for those who can't spell
 Liszt or Shostakovitch.
 .
 Given a search pattern and a string, this algorithm determines whether the
 string contains a substring that matches the pattern up to a parameterizable
 number N of "errors". An "error" is either a substitution (replace a
 character of the string with another character), a deletion (remove a
 character) or an insertion (add a character to the string). In more
 scientific terms, the number of errors is the Levenshtein edit distance
 between the pattern and the matched substring.
 .
 The search patterns are roughly those of the Unix shell, including
 one-character wildcard (?), character classes ([0-9]) and multi-character
 wildcard (*). In addition, conjunction (&) and alternative (|) are supported.
 General regular expressions are not supported, however.
 .
 This package contains all the development stuff you need to use
 the agrep OCaml library in your programs.
