This is primarily for use with file IO. Rather than write out the specific attributes/connections required to maintain a relationship, a description of the related nodes/plugs is written instead. The relationship must have an owner node, and have a specific type. During file read, maya will make the connections necessary to represent the realtionship in the dependency graph.
Break the specified relationship instead of creating it Flag can have multiple arguments, passed either as a tuple or a list.
Derived from mel command maya.cmds.relationship
