       This plugin probes for the existence of the given command line program.

       Alien::Build::Plugin::Probe::CommandLine - Probe for tools or commands already available

command
       The name of the command.

   args
       The arguments to pass to the command.

   secondary
       If you are using another probe plugin (such as Alien::Build::Plugin::Probe::CBuilder or
       Alien::Build::Plugin::PkgConfig::Negotiate) to detect the existence of a library, but also need a program
       to exist, then you should set secondary to a true value.  For example when you need both:

        use alienfile;
        # requires both liblzma library and xz program
        plugin 'PkgConfig' => 'liblzma';
        plugin 'Probe::CommandLine' => (
          command   => 'xz',
          secondary => 1,
        );

       When you don't:

        use alienfile;
        plugin 'Probe::CommandLine' => (
          command   => 'gzip',
          secondary => 0, # default
        );

   match
       Regular expression for which the program output should match.

   match_stderr
       Regular expression for which the program standard error should match.

   version
       Regular expression to parse out the version from the program output.  The regular expression should store
       the version number in $1.

   version_stderr
       Regular expression to parse out the version from the program standard error.  The regular expression
       should store the version number in $1.

   atleast_version
       The minimum required version as provided by the system.

       Alien::Build, alienfile, Alien::Build::MM, Alien

        use alienfile;
        plugin 'Probe::CommandLine' => (
          command => 'gzip',
          args    => [ '--version' ],
          match   => qr/gzip/,
          version => qr/gzip ([0-9\.]+)/,
        );
