This modules provides RegexMaker and RegexLike instances for using String with the DFA backend (Text.Regex.Lib.WrapDFAEngine and Text.Regex.Lazy.DFAEngine). This module is usually used via import Text.Regex.DFA.

This exports instances of the high level API and the medium level API of compile,execute, and regexec.
