-// --- A note about thread-safety:
-//
-// We describe many functions in this routine as being thread-hostile,
-// thread-compatible, or thread-safe.  Here are the meanings we use:
-//
-// thread-safe: it is safe for multiple threads to call this routine
-//   (or, when referring to a class, methods of this class)
-//   concurrently.
-// thread-hostile: it is not safe for multiple threads to call this
-//   routine (or methods of this class) concurrently.  In gflags,
-//   most thread-hostile routines are intended to be called early in,
-//   or even before, main() -- that is, before threads are spawned.
-// thread-compatible: it is safe for multiple threads to read from
-//   this variable (when applied to variables), or to call const
-//   methods of this class (when applied to classes), as long as no
-//   other thread is writing to the variable or calling non-const
-//   methods of this class.

-// Now come the command line flag declaration/definition macros that

-// for this is initialization: we want people to be able to access
-// variables in global constructors and have that not crash, even if
-// their global constructor runs before the global constructor here.
-// (Obviously, we can't guarantee the flags will have the correct
-// default value in that case, but at least accessing them is safe.)
-// The only way to do that is have flags point to a static buffer.
-// So we make one, using a union to ensure proper alignment, and
-// then use placement-new to actually set up the flag with the
-// correct default value.  In the same vein, we have to worry about
-// flag access in global destructors, so FlagRegisterer has to be
-// careful never to destroy the flag-values it constructs.
-//
-// Note that when we define a flag variable FLAGS_<name>, we also
-// preemptively define a junk variable, FLAGS_no<name>.  This is to
-// cause a link-time error if someone tries to define 2 flags with
-// names like "logging" and "nologging".  We do this because a bool
-// flag FLAG can be set from the command line to true with a "-FLAG"
-// argument, and to false with a "-noFLAG" argument, and so this can
-// potentially avert confusion.
-//
-// We also put flags into their own namespace.  It is purposefully
-// named in an opaque way that people should have trouble typing
-// directly.  The idea is that DEFINE puts the flag in the weird
-// namespace, and DECLARE imports the flag from there into the current
-// namespace.  The net result is to force people to use DECLARE to get
-// access to a flag, rather than saying "extern GFLAGS_DLL_DECL bool FLAGS_whatever;"
-// or some such instead.  We want this so we can put extra
-// functionality (like sanity-checking) in DECLARE if we want, and
-// make sure it is picked up everywhere.

-// people can't DECLARE_int32 something that they DEFINE_bool'd
