+Each element is of the form:

+REPLACEMENT... is interpreted the same way the value of a `face' text
+property is: it may be (1) A face name, (2) A list of face names, (3) A
+property-list of face attribute/value pairs, or (4) A list of face names
+intermixed with lists containing face attribute/value pairs.
+
+Multiple entries in REPLACEMENT... are merged together to form the final
+result, with faces or attributes earlier in the list taking precedence

+
+Face-name remapping cycles are suppressed; recursive references use the
+underlying face instead of the remapped face. So a remapping of the form:
+
+ (FACE EXTRA-FACE... FACE)
+
+or:
+
+ (FACE (FACE-ATTR VAL ...) FACE)
+
+will cause EXTRA-FACE... or (FACE-ATTR VAL ...) to be _merged_ with the
+existing definition of FACE. Note that for the default face, this isn't
+necessary, as every face inherits from the default face.
+
+Making this variable buffer-local is a good way to allow buffer-specific
+face definitions. For instance, the mode my-mode could define a face
