=head1 NAME VM::EC2::REST::general

=head1 SYNOPSIS

 use VM::EC2 'general';

=head1 METHODS

These are EC2 methods that Amazon calls "general".

Implemented:
 GetConsoleOutput
 DescribeAccountAttributes

Unimplemented:
 (none)

=head2 $output = $ec2->get_console_output(-instance_id=>'i-12345')

=head2 $output = $ec2->get_console_output('i-12345');

Returns the console output of the indicated instance. The output is
actually a VM::EC2::ConsoleOutput object, but it is
overloaded so that when treated as a string it will appear as a
large text string containing the  console output. When treated like an
object it provides instanceId() and timestamp() methods.
