NAME
       Sys::VirtConvert::ExecHelper - Execute a command with output
       suppression

SYNOPSIS
	use Sys::VirtConvert::ExecHelper;

	$eh = Sys::VirtConvert::ExecHelper->run('rpm', '-V', 'bash');

	if($eh->status() != 0) {
	    warn $eh->output();
	}

DESCRIPTION
       Sys::VirtConvert::ExecHelper is a substitute for system() when you
       don't want any command output. Sys::VirtConvert::ExecHelper does,
       however, make STDOUT and STDERR available in a combined stream if it is
       required, for example because the executed command failed.

METHODS
       run(@command)
	   Run @command, which is an array containing the command and its
	   arguments.

	   The command will be executed immediately. ExecHelper will block
	   until the command exits.

       status
	   Return the exit status of the executed command.

       output
	   Return the combined stdout and stderr of the command.

	   WARNING: This command puts the output in a string in memory. Don't
	   use this if the output could be large.
