A systems integration framework, built to bring the benefits of configuration management to your entire infrastructure.

Chef::ResourceCollection::ResourceSet#resources

Find existing resources by searching the list of existing resources.  Possible
forms are:

find(:file => "foobar")
find(:file => [ "foobar", "baz" ])
find("file[foobar]", "file[baz]")
find("file[foobar,baz]")

Returns the matching resource, or an Array of matching resources.

Raises an ArgumentError if you feed it bad lookup information
Raises a Runtime Error if it can't find the resources you are looking for.
resources is a poorly named, but we have to maintain it for back
compat.
