Guide book or advice for Los Pericos in Puebla, Mexico?

I'm planning a December trip to climb Pico de Orizaba in Mexico and toying with the idea of hitting a sport crag on the way back to Mexico City afterwards. Looks like Los Pericos is on the way as it's near Puebla. I can't seem to find much information about it online though. Does anyone have useful links of know of any guidebooks that mention it?

Thanks,
