+// directly give them their exact sizes. We don't need to worry about
+// endianness because these are just the types in the YAMLIO structures,
+// and are appropriately converted to the necessary endianness when
+// reading/generating binary object files.
+// The naming of these types is intended to be ELF_PREFIX, where PREFIX is
+// the common prefix of the respective constants. E.g. ELF_EM corresponds
+// to the `e_machine` constants, like `EM_X86_64`.
+// In the future, these would probably be better suited by C++11 enum
+// class's with appropriate fixed underlying type.
