Finding a Point Relative to a Bone

I know this is probably a total newbie question but here we go.

I know the following

• I have a SkinnedMeshRenderer

• There is a mesh associated with the SkinnedMeshRenderer

• There is a single bone associated with the SkinnedMeshRenderer

• I know the start position for a point in the mesh

How do I determine the new position of the point based on the movement of the bone?
