+Summary Format Matching On Pointers
+----------------------
+
+When a summary format is registered for a type ``T``, lldb will apply this
+format to both ``T`` and ``T*``. -p options could prevent lldb from using this
+format to type ``T*``. When -p options is not given, users can use the -d
option
+to specify how many layer of pointers can be dereferenced at most when matching
+the format of type ``T`` (default to 1). It should be noted that the value
+object passed to the summary format won't dereferenced at all.
