Wake from sleep via ssh/terminal? ML

Anyone know a way to wake a Mac from sleep via ssh/terminal?

I have a remote access app that has a bug right now that if the system goes to sleep it cannot wake it and their solution is to disable any sleep functions until they can figure out a fix.

While I did have the sleep functions disabled and just kept the screen brightness as low as possible and a screen saver set to kick in quickly for my iMac, since I reinstalled with ML the other day after my OEM hard drive died, I forgot to disable sleep.

Now I don't have physical access to my iMac and want to remotely access it so I need to figure out a way via ssh/terminal to kick it out of sleep preferably without rebooting it, though I can do so if there is no other option.

I know you can kick a Mac into sleep using the command

But I want to accomplish the opposite result.

Any suggestions?
