-// This file contains code for handling the 'reporting' flags.  These
-// are flags that, when present, cause the program to report some
-// information and then exit.  --help and --version are the canonical
-// reporting flags, but we also have flags like --helpxml, etc.
-//
-// There's only one function that's meant to be called externally:
-// HandleCommandLineHelpFlags().  (Well, actually, ShowUsageWithFlags(),
-// ShowUsageWithFlagsRestrict(), and DescribeOneFlag() can be called
-// externally too, but there's little need for it.)  These are all
-// declared in the main gflags.h header file.
-//
-// HandleCommandLineHelpFlags() will check what 'reporting' flags have
-// been defined, if any -- the "help" part of the function name is a
-// bit misleading -- and do the relevant reporting.  It should be
-// called after all flag-values have been assigned, that is, after
-// parsing the command-line.

-//
-// A simple mutex wrapper, supporting locks and read-write locks.
-// You should assume the locks are *not* re-entrant.
-//
-// This class is meant to be internal-only and should be wrapped by an
-// internal namespace.  Before you use this module, please give the
-// name of your internal namespace for this module.  Or, if you want
-// to expose it, you'll want to move it to the Google namespace.  We
-// cannot put this class in global namespace because there can be some
-// problems when we have multiple versions of Mutex in each shared object.
-//
-// NOTE: by default, we have #ifdef'ed out the TryLock() method.
-//       This is for two reasons:
-// 1) TryLock() under Windows is a bit annoying (it requires a
-//    #define to be defined very early).
-// 2) TryLock() is broken for NO_THREADS mode, at least in NDEBUG
-//    mode.
-// If you need TryLock(), and either these two caveats are not a
-// problem for you, or you're willing to work around them, then
-// feel free to #define GMUTEX_TRYLOCK, or to remove the #ifdefs
-// in the code below.
-//
-// CYGWIN NOTE: Cygwin support for rwlock seems to be buggy:
-//    http://www.cygwin.com/ml/cygwin/2008-12/msg00017.html
-// Because of that, we might as well use windows locks for
-// cygwin.  They seem to be more reliable than the cygwin pthreads layer.
-//
-// TRICKY IMPLEMENTATION NOTE:
-// This class is designed to be safe to use during
-// dynamic-initialization -- that is, by global constructors that are
-// run before main() starts.  The issue in this case is that
-// dynamic-initialization happens in an unpredictable order, and it
-// could be that someone else's dynamic initializer could call a
-// function that tries to acquire this mutex -- but that all happens
-// before this mutex's constructor has run.  (This can happen even if
-// the mutex and the function that uses the mutex are in the same .cc
-// file.)  Basically, because Mutex does non-trivial work in its
-// constructor, it's not, in the naive implementation, safe to use
-// before dynamic initialization has run on it.
-//
-// The solution used here is to pair the actual mutex primitive with a
-// bool that is set to true when the mutex is dynamically initialized.
-// (Before that it's false.)  Then we modify all mutex routines to
-// look at the bool, and not try to lock/unlock until the bool makes
-// it to true (which happens after the Mutex constructor has run.)
-//
-// This works because before main() starts -- particularly, during
-// dynamic initialization -- there are no threads, so a) it's ok that
-// the mutex operations are a no-op, since we don't need locking then
-// anyway; and b) we can be quite confident our bool won't change
-// state between a call to Lock() and a call to Unlock() (that would
-// require a global constructor in one translation unit to call Lock()
-// and another global constructor in another translation unit to call
-// Unlock() later, which is pretty perverse).
-//
-// That said, it's tricky, and can conceivably fail; it's safest to
-// avoid trying to acquire a mutex in a global constructor, if you
-// can.  One way it can fail is that a really smart compiler might
-// initialize the bool to true at static-initialization time (too
-// early) rather than at dynamic-initialization time.  To discourage
-// that, we set is_safe_ to true in code (not the constructor
-// colon-initializer) and set it to true via a function that always
-// evaluates to true, but that the compiler can't know always
-// evaluates to true.  This should be good enough.
-//
-// A related issue is code that could try to access the mutex
-// after it's been destroyed in the global destructors (because
-// the Mutex global destructor runs before some other global
-// destructor, that tries to acquire the mutex).  The way we
-// deal with this is by taking a constructor arg that global
-// mutexes should pass in, that causes the destructor to do no
-// work.  We still depend on the compiler not doing anything
-// weird to a Mutex's memory after it is destroyed, but for a
-// static global variable, that's pretty safe.

-// This file is needed for windows -- unittests are not part of the
-// gflags dll, but still want to include config.h just like the
-// dll does, so they can use internal tools and APIs for testing.
-//
-// The problem is that config.h declares GFLAGS_DLL_DECL to be
-// for exporting symbols, but the unittest needs to *import* symbols
-// (since it's not the dll).
-//
-// The solution is to have this file, which is just like config.h but
-// sets GFLAGS_DLL_DECL to do a dllimport instead of a dllexport.
-//
-// The reason we need this extra GFLAGS_DLL_DECL_FOR_UNITTESTS
-// variable is in case people want to set GFLAGS_DLL_DECL explicitly
-// to something other than __declspec(dllexport).  In that case, they
-// may want to use something other than __declspec(dllimport) for the
-// unittest case.  For that, we allow folks to define both
-// GFLAGS_DLL_DECL and GFLAGS_DLL_DECL_FOR_UNITTESTS explicitly.
-//
-// NOTE: This file is equivalent to config.h on non-windows systems,
-// which never defined GFLAGS_DLL_DECL_FOR_UNITTESTS and always
-// define GFLAGS_DLL_DECL to the empty string.
