NAME
       Alien::Build::Plugin::Prefer::BadVersion - Plugin to filter out known
       bad versions

VERSION
       version 2.80

SYNOPSIS
        use alienfile;
        plugin 'Prefer::BadVersion' => '1.2.3';

DESCRIPTION
       This plugin allows you to easily filter out known bad versions of
       libraries in a share install.  It doesn't affect a system install at
       all.  You need a Prefer plugin that filters and sorts files first.  You
       may specify the filter in one of three ways:

       as a string
           Filter out any files that match the given version.

            use alienfile;
            plugin 'Prefer::BadVersion' => '1.2.3';

       as an array
           Filter out all files that match any of the given versions.

            use alienfile;
            plugin 'Prefer::BadVersion' => [ '1.2.3', '1.2.4' ];

       as a code reference
           Filter out any files return a true value.

            use alienfile;
            plugin 'Prefer::BadVersion' => sub {
              my($file) = @_;
              $file->{version} eq '1.2.3'; # same as the string version above
            };

       This plugin can also be used to filter out known bad versions of a
       library on just one platform.  For example, if you know that version
       1.2.3 if bad on windows, but okay on other platforms:

        use alienfile;
        plugin 'Prefer::BadVersion' => '1.2.3' if $^O eq 'MSWin32';

PROPERTIES
   filter
       Filter out entries that match the filter.

CAVEATS
       If you are using the string or array mode, then you need an existing
       Prefer plugin that sets the version number for each file candidate,
       such as Alien::Build::Plugin::Prefer::SortVersions.

       Unless you want to exclude the latest version from a share install,
       this plugin isn't really that useful.  It has no effect on system
       installs, which may not be obvious at first.
