@mzlib[#:mode title pregexp]

@deprecated[@racketmodname[racket/base]]{}

The @racketmodname[mzlib/pregexp] library provides wrappers around
@racket[regexp-match], @|etc| that coerce string and byte-string
arguments to @racket[pregexp] matchers instead of @racket[regexp]
matchers.

The library also re-exports: @racket[pregexp], and it re-exports
@racket[regexp-quote] as @racket[pregexp-quote].

argument is compiled via @racket[pregexp], and a byte string
@racket[pattern] argument is compiled via @racket[byte-pregexp].}
