[chef] list of cloud providers supported by Chef?

[Florin Andrei < >]

According to this page...

http://www.getchef.com/solutions/cloud-management/

..."Chef is integrated with all major cloud providers including Amazon 
EC2, VMWare, IBM Smartcloud, Rackspace, OpenStack, Windows Azure, HP 
Cloud, Google Compute Engine, Joyent Cloud and others."

What does "and others" mean? Where can I find a list of all cloud 
providers that Chef is integrated with? (along with documentation for 
each supported provider)

Thanks.
