  The version of this module was broken
    Amon2::DBI 0.31 has bug.

        Broken,
        http://weblog.bulknews.net/post/33907905561/do-not-ship-modules-with
        -module-install-1-04

  Recommended XS module for better performance
    JSON::XS is recommended
        If you are using JSON.

    HTTP::Parser::XS is recommended
        If you are using Plack.

    Linux::Inotify2 is recommended
        If you are using Filesys::Notify::Simple.
