+a record type from Storable instances of its elements in an elegant way.
+It does not do any magic, just a bit arithmetic to compute the right
+offsets, that would be otherwise done manually or by a preprocessor like
+C2HS. There is no guarantee that the generated memory layout is
+compatible with that of a corresponding C struct. However, the module
+generates the smallest layout that is possible with respect to the
+alignment of the record elements.")
