[Pkg-haskell-maintainers] Bug#772911: Bug#772911: fails to run program +>><<[>>, .<<]

[Joachim Breitner]

Hi Joey,

thanks for your report. According to
http://hackage.haskell.org/package/brainfuck
hsbrainfuck is unmaintained, so there is probably not much going to
happen about this (besides, maybe, the removal of this package from
Debian).

Greetings,
Joachim
