Managing Multiple AWS Accounts using EB deploy

I am working on two different projects for two different companies. Each of them gave me access to their AWS management console to deploy Ruby applications. I'm writing the code on my Mac OS/X. I can't see where to change the configuration for the eb commands to point to the different accounts. I did eb init, but it seems to point to the same AWS account and creates the application and server instance on that account. Can someone please help or guide me to instructions when using two different AWS accounts for two different projects and trying to deploy using the eb command?

Thanks,
