-/// \brief Wrapper object for manipulating Mach-O object files.
-///
-/// This class is designed to implement a full-featured, efficient, portable,
-/// and robust Mach-O interface to Mach-O object files. It does not attempt to
-/// smooth over rough edges in the Mach-O format or generalize access to object
-/// independent features.
-///
-/// The class is designed around accessing the Mach-O object which is expected
-/// to be fully loaded into memory.
-///
-/// This class is *not* suitable for concurrent use. For efficient operation,
-/// the class uses APIs which rely on the ability to cache the results of
-/// certain calls in internal objects which are not safe for concurrent
-/// access. This allows the API to be zero-copy on the common paths.
-//
-// FIXME: It would be cool if we supported a "paged" MemoryBuffer
-// implementation. This would allow us to implement a more sensible version of
-// MemoryObject which can work like a MemoryBuffer, but be more efficient for
-// objects which are in the current address space.
