/// Execute the specified command with the given argument and options

/// <p>
/// Usage:
/// <pre>
/// runCommand(command)
/// runCommand(command, arg1, ..., argN)
/// runCommand(command, arg1, ..., argN, options)
/// </pre>
/// All except the last arguments to runCommand are converted to strings
/// and denote command name and its arguments. If the last argument is a
/// JavaScript object, it is an option object. Otherwise it is converted to
/// string denoting the last argument and options objects assumed to be
/// empty.
/// The following properties of the option object are processed:
/// <ul>
/// <li><tt>args</tt> - provides an array of additional command arguments
/// <li><tt>env</tt> - explicit environment object. All its enumerable
/// properties define the corresponding environment variable names.
/// <li><tt>input</tt> - the process input. If it is not
/// java.io.InputStream, it is converted to string and sent to the process
/// as its input. If not specified, no input is provided to the process.
/// <li><tt>output</tt> - the process output instead of
/// java.lang.System.out. If it is not instance of java.io.OutputStream,
/// the process output is read, converted to a string, appended to the
/// output property value converted to string and put as the new value of
/// the output property.
/// <li><tt>err</tt> - the process error output instead of
/// java.lang.System.err. If it is not instance of java.io.OutputStream,
/// the process error output is read, converted to a string, appended to
/// the err property value converted to string and put as the new
/// value of the err property.
