[Bf-python] Armature : in Class editBone there is no variable "children"

[Joseph Gilbert]

Sorry, the armature building code is better for gui's than scripting.

You can get the parent/child relationship from the bones before entering  
editmode as campell has suggested. If that's not the case than someone  
should go ahead and add the read-only attribute.
