scroll 1.20150314 released with these changes

  • This is a post-7drl release that does not change any gameplay.
  • Support use as a pager, with input piped in on stdin, as long as the unix module is available.
  • Rename Setup.hs since cabal uses that name. Thanks to Sergei Trofimovich of Gentoo, which has packaged scroll!
  • Don't crash on exceedingly small input files when being used as a pager.
