[Haskell-cafe] ANNOUNCE: Frown, Ralf Hinze's LALR(k) parser generator for Haskell, now slightly upkept ☺

[M Farkas-Dyck]

Some years ago, Ralf Hinze wrote this parser generator [0], and i have
since been using it, so i cleaned it up and uploaded it to Hackage as
"frown" [1].

My repo is here: https://github.com/strake/frown
