NAME
    System2 - like system(), but with STDERR available as well

SYNOPSIS
      use System2;

      $System2::debug++;

      my ($out, $err) = system2(@args);
      my ($exit_value, $signal_num, $dumped_core) = &System2::exit_status($?);
      
      print "EXIT: exit_value $exit_value signal_num ".
            "$signal_num dumped_core $dumped_core\n";
      
      print "OUT:\n$out";
      print "ERR:\n$err"

DESCRIPTION
    Execute a command, and returns output from STDOUT and STDERR. Much like
    system(). $? is set. (Much cheaper than using open3() to get the same
    info.)

    If $debug is set, on-the fly diagnostics will be reported about how much
    data is being read.

    Provides for convienence, a routine exit_status() to break out the exit
    value into:

      - the exit value of the subprocess
      - which signal, if any, the process died from
      - reports whether there was a core dump.

    All right from perlvar(1), so no surprises.

CAVEATS
    Although I've been using this module for literally years now personally,
    consider it lightly tested, until I get feedback from the public at
    large.

    Have at it.
