synopsis:               Pure Haskell Tagged DFA Backend for "Text.Regex" (regex-base)
description:
  This package provides a pure Haskell \"Tagged\" DFA regex engine for <//hackage.haskell.org/package/regex-base regex-base>. This implementation was inspired by the algorithm (and Master's thesis) behind the regular expression library known as <https://github.com/laurikari/tre/ TRE or libtre>.
  .
  Please consult the "Text.Regex.TDFA" module for API documentation including a tutorial with usage examples;
  see also <https://wiki.haskell.org/Regular_expressions> for general information about regular expression support in Haskell.
