-// This file is a compatibility layer that defines Google's version of
-// command line flags that are used for configuration.
-//
-// We 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 bool FLAGS_logtostderr;
-// 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.
-//
-// We also put the type of the variable in the namespace, so that
-// people can't DECLARE_int32 something that they DEFINE_bool'd
-// elsewhere.

-//
-// A simple mutex wrapper, supporting locks and read-write locks.
-// You should assume the locks are *not* re-entrant.
-//
-// To use: you should define the following macros in your configure.ac:
-//   ACX_PTHREAD
-//   AC_RWLOCK
-// The latter is defined in ../autoconf.
-//
-// 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.

-// This file is needed for windows -- unittests are not part of the
-// glog 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 GOOGLE_GLOG_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 GOOGLE_GLOG_DLL_DECL to do a dllimport instead of a dllexport.
-//
-// The reason we need this extra GOOGLE_GLOG_DLL_DECL_FOR_UNITTESTS
-// variable is in case people want to set GOOGLE_GLOG_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
-// GOOGLE_GLOG_DLL_DECL and GOOGLE_GLOG_DLL_DECL_FOR_UNITTESTS explicitly.
-//
-// NOTE: This file is equivalent to config.h on non-windows systems,
-// which never defined GOOGLE_GLOG_DLL_DECL_FOR_UNITTESTS and always
-// define GOOGLE_GLOG_DLL_DECL to the empty string.

-// Implementation note: the following code is a straightforward
-// translation of the Itanium C++ ABI defined in BNF with a couple of
-// exceptions.
-//
-// - Support GNU extensions not defined in the Itanium C++ ABI
-// - <prefix> and <template-prefix> are combined to avoid infinite loop
-// - Reorder patterns to shorten the code
-// - Reorder patterns to give greedier functions precedence
-//   We'll mark "Less greedy than" for these cases in the code
-//
-// Each parsing function changes the state and returns true on
-// success.  Otherwise, don't change the state and returns false.  To
-// ensure that the state isn't changed in the latter case, we save the
-// original state before we call more than one parsing functions
-// consecutively with &&, and restore the state if unsuccessful.  See
-// ParseEncoding() as an example of this convention.  We follow the
-// convention throughout the code.
-//
-// Originally we tried to do demangling without following the full ABI
-// syntax but it turned out we needed to follow the full syntax to
-// parse complicated cases like nested template arguments.  Note that
-// implementing a full-fledged demangler isn't trivial (libiberty's
-// cp-demangle.c has +4300 lines).
-//
-// Note that (foo) in <(foo) ...> is a modifier to be ignored.

-// An async-signal-safe and thread-safe demangler for Itanium C++ ABI
-// (aka G++ V3 ABI).
-
-// The demangler is implemented to be used in async signal handlers to
-// symbolize stack traces.  We cannot use libstdc++'s
-// abi::__cxa_demangle() in such signal handlers since it's not async
-// signal safe (it uses malloc() internally).
-//
-// Note that this demangler doesn't support full demangling.  More
-// specifically, it doesn't print types of function parameters and
-// types of template arguments.  It just skips them.  However, it's
-// still very useful to extract basic information such as class,
-// function, constructor, destructor, and operator names.
-//
-// See the implementation note in demangle.cc if you are interested.
-//
-// Example:
-//
-// | Mangled Name  | The Demangler | abi::__cxa_demangle()
-// |---------------|---------------|-----------------------
-// | _Z1fv         | f()           | f()
-// | _Z1fi         | f()           | f(int)
-// | _Z3foo3bar    | foo()         | foo(bar)
-// | _Z1fIiEvi     | f<>()         | void f<int>(int)
-// | _ZN1N1fE      | N::f          | N::f
-// | _ZN3Foo3BarEv | Foo::Bar()    | Foo::Bar()
-// | _Zrm1XS_"     | operator%()   | operator%(X, X)
-// | _ZN3FooC1Ev   | Foo::Foo()    | Foo::Foo()
-// | _Z1fSs        | f()           | f(std::basic_string<char,
-// |               |               |   std::char_traits<char>,
-// |               |               |   std::allocator<char> >)
-//
-// See the unit test for more examples.
-//
-// Note: we might want to write demanglers for ABIs other than Itanium
-// C++ ABI in the future.

-// Make a bunch of macros for logging.  The way to log things is to stream
-// things to LOG(<a particular severity level>).  E.g.,
-//
-//   LOG(INFO) << "Found " << num_cookies << " cookies";
-//
-// You can capture log messages in a string, rather than reporting them
-// immediately:
-//
-//   vector<string> errors;
-//   LOG_STRING(ERROR, &errors) << "Couldn't parse cookie #" << cookie_num;
-//
-// This pushes back the new error onto 'errors'; if given a NULL pointer,
-// it reports the error via LOG(ERROR).
-//
-// You can also do conditional logging:
-//
-//   LOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
-//
-// You can also do occasional logging (log every n'th occurrence of an
-// event):
-//
-//   LOG_EVERY_N(INFO, 10) << "Got the " << google::COUNTER << "th cookie";
-//
-// The above will cause log messages to be output on the 1st, 11th, 21st, ...
-// times it is executed.  Note that the special google::COUNTER value is used
-// to identify which repetition is happening.
-//
-// You can also do occasional conditional logging (log every n'th
-// occurrence of an event, when condition is satisfied):
-//
-//   LOG_IF_EVERY_N(INFO, (size > 1024), 10) << "Got the " << google::COUNTER
-//                                           << "th big cookie";
-//
-// You can log messages the first N times your code executes a line. E.g.
-//
-//   LOG_FIRST_N(INFO, 20) << "Got the " << google::COUNTER << "th cookie";
-//
-// Outputs log messages for the first 20 times it is executed.
-//
-// Analogous SYSLOG, SYSLOG_IF, and SYSLOG_EVERY_N macros are available.
-// These log to syslog as well as to the normal logs.  If you use these at
-// all, you need to be aware that syslog can drastically reduce performance,
-// especially if it is configured for remote logging!  Don't use these
-// unless you fully understand this and have a concrete need to use them.
-// Even then, try to minimize your use of them.
-//
-// There are also "debug mode" logging macros like the ones above:
-//
-//   DLOG(INFO) << "Found cookies";
-//
-//   DLOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
-//
-//   DLOG_EVERY_N(INFO, 10) << "Got the " << google::COUNTER << "th cookie";
-//
-// All "debug mode" logging is compiled away to nothing for non-debug mode
-// compiles.
-//
-// We also have
-//
-//   LOG_ASSERT(assertion);
-//   DLOG_ASSERT(assertion);
-//
-// which is syntactic sugar for {,D}LOG_IF(FATAL, assert fails) << assertion;
-//
-// There are "verbose level" logging macros.  They look like
-//
-//   VLOG(1) << "I'm printed when you run the program with --v=1 or more";
-//   VLOG(2) << "I'm printed when you run the program with --v=2 or more";
-//
-// These always log at the INFO log level (when they log at all).
-// The verbose logging can also be turned on module-by-module.  For instance,
-//    --vmodule=mapreduce=2,file=1,gfs*=3 --v=0
-// will cause:
-//   a. VLOG(2) and lower messages to be printed from mapreduce.{h,cc}
-//   b. VLOG(1) and lower messages to be printed from file.{h,cc}
-//   c. VLOG(3) and lower messages to be printed from files prefixed with "gfs"
-//   d. VLOG(0) and lower messages to be printed from elsewhere
-//
-// The wildcarding functionality shown by (c) supports both '*' (match
-// 0 or more characters) and '?' (match any single character) wildcards.
-//
-// There's also VLOG_IS_ON(n) "verbose level" condition macro. To be used as
-//
-//   if (VLOG_IS_ON(2)) {
-//     // do some logging preparation and logging
-//     // that can't be accomplished with just VLOG(2) << ...;
-//   }
-//
-// There are also VLOG_IF, VLOG_EVERY_N and VLOG_IF_EVERY_N "verbose level"
-// condition macros for sample cases, when some extra computation and
-// preparation for logs is not needed.
-//   VLOG_IF(1, (size > 1024))
-//      << "I'm printed when size is more than 1024 and when you run the "
-//         "program with --v=1 or more";
-//   VLOG_EVERY_N(1, 10)
-//      << "I'm printed every 10th occurrence, and when you run the program "
-//         "with --v=1 or more. Present occurence is " << google::COUNTER;
-//   VLOG_IF_EVERY_N(1, (size > 1024), 10)
-//      << "I'm printed on every 10th occurence of case when size is more "
-//         " than 1024, when you run the program with --v=1 or more. ";
-//         "Present occurence is " << google::COUNTER;
-//
-// The supported severity levels for macros that allow you to specify one
-// are (in increasing order of severity) INFO, WARNING, ERROR, and FATAL.
-// Note that messages of a given severity are logged not only in the
-// logfile for that severity, but also in all logfiles of lower severity.
-// E.g., a message of severity FATAL will be logged to the logfiles of
-// severity FATAL, ERROR, WARNING, and INFO.
-//
-// There is also the special severity of DFATAL, which logs FATAL in
-// debug mode, ERROR in normal mode.
-//
-// Very important: logging a message at the FATAL severity level causes
-// the program to terminate (after the message is logged).
-//
-// Unless otherwise specified, logs will be written to the filename
-// "<program name>.<hostname>.<user name>.log.<severity level>.", followed
-// by the date, time, and pid (you can't prevent the date, time, and pid
-// from being in the filename).
-//
-// The logging code takes two flags:
-//     --v=#           set the verbose level
-//     --logtostderr   log all the messages to stderr instead of to logfiles
-
-// LOG LINE PREFIX FORMAT
-//
-// Log lines have this form:
-//
-//     Lyyyymmdd hh:mm:ss.uuuuuu threadid file:line] msg...
-//
-// where the fields are defined as follows:
-//
-//   L                A single character, representing the log level
-//                    (eg 'I' for INFO)
-//   yyyy             The year
-//   mm               The month (zero padded; ie May is '05')
-//   dd               The day (zero padded)
-//   hh:mm:ss.uuuuuu  Time in hours, minutes and fractional seconds
-//   threadid         The space-padded thread ID as returned by GetTID()
-//                    (this matches the PID on Linux)
-//   file             The file name
-//   line             The line number
-//   msg              The user-supplied message
-//
-// Example:
-//
-//   I1103 11:57:31.739339 24395 google.cc:2341] Command line: ./some_prog
-//   I1103 11:57:31.739403 24395 google.cc:2342] Process id 24395
-//
-// NOTE: although the microseconds are useful for comparing events on
-// a single machine, clocks on different machines may not be well
-// synchronized.  Hence, use caution when comparing the low bits of
-// timestamps from different machines.

-// Even this solution has problems -- it may pull unintended operators into the

-// Author: Ray Sidney and many others

-// Defines the VLOG_IS_ON macro that controls the variable-verbosity
-// conditional logging.
-//
-// It's used by VLOG and VLOG_IF in logging.h
-// and by RAW_VLOG in raw_logging.h to trigger the logging.
-//
-// It can also be used directly e.g. like this:
-//   if (VLOG_IS_ON(2)) {
-//     // do some logging preparation and logging
-//     // that can't be accomplished e.g. via just VLOG(2) << ...;
-//   }
-//
-// The truth value that VLOG_IS_ON(level) returns is determined by 
-// the three verbosity level flags:
-//   --v=<n>  Gives the default maximal active V-logging level;
-//            0 is the default.
-//            Normally positive values are used for V-logging levels.
-//   --vmodule=<str>  Gives the per-module maximal V-logging levels to override
-//                    the value given by --v.
-//                    E.g. "my_module=2,foo*=3" would change the logging level
-//                    for all code in source files "my_module.*" and "foo*.*"
-//                    ("-inl" suffixes are also disregarded for this matching).
-//
-// SetVLOGLevel helper function is provided to do limited dynamic control over
-// V-logging by overriding the per-module settings given via --vmodule flag.
-//
-// CAVEAT: --vmodule functionality is not available in non gcc compilers.

-// This library provides Symbolize() function that symbolizes program

-// This library has a minimal implementation of an ELF symbol table
-// reader (i.e. it doesn't depend on libelf, etc.).
-//
-// The algorithm used in Symbolize() is as follows.
-//
-//   1. Go through a list of maps in /proc/self/maps and find the map
-//   containing the program counter.
-//

-//    malloc() from the unwinder.  This is a problem because we're
-//    trying to use the unwinder to instrument malloc().
-//
-// 4) The Windows API CaptureStackTrace.

-// Note: if you add a new implementation here, make sure it works
-// correctly when GetStackTrace() is called with max_depth == 0.

-// Make a bunch of macros for logging.  The way to log things is to stream
-// things to LOG(<a particular severity level>).  E.g.,
-//
-//   LOG(INFO) << "Found " << num_cookies << " cookies";
-//
-// You can capture log messages in a string, rather than reporting them
-// immediately:
-//
-//   vector<string> errors;
-//   LOG_STRING(ERROR, &errors) << "Couldn't parse cookie #" << cookie_num;
-//
-// This pushes back the new error onto 'errors'; if given a NULL pointer,
-// it reports the error via LOG(ERROR).
-//
-// You can also do conditional logging:
-//
-//   LOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
-//
-// You can also do occasional logging (log every n'th occurrence of an
-// event):
-//
-//   LOG_EVERY_N(INFO, 10) << "Got the " << google::COUNTER << "th cookie";
-//
-// The above will cause log messages to be output on the 1st, 11th, 21st, ...
-// times it is executed.  Note that the special google::COUNTER value is used
-// to identify which repetition is happening.
-//
-// You can also do occasional conditional logging (log every n'th
-// occurrence of an event, when condition is satisfied):
-//
-//   LOG_IF_EVERY_N(INFO, (size > 1024), 10) << "Got the " << google::COUNTER
-//                                           << "th big cookie";
-//
-// You can log messages the first N times your code executes a line. E.g.
-//
-//   LOG_FIRST_N(INFO, 20) << "Got the " << google::COUNTER << "th cookie";
-//
-// Outputs log messages for the first 20 times it is executed.
-//
-// Analogous SYSLOG, SYSLOG_IF, and SYSLOG_EVERY_N macros are available.
-// These log to syslog as well as to the normal logs.  If you use these at
-// all, you need to be aware that syslog can drastically reduce performance,
-// especially if it is configured for remote logging!  Don't use these
-// unless you fully understand this and have a concrete need to use them.
-// Even then, try to minimize your use of them.
-//
-// There are also "debug mode" logging macros like the ones above:
-//
-//   DLOG(INFO) << "Found cookies";
-//
-//   DLOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
-//
-//   DLOG_EVERY_N(INFO, 10) << "Got the " << google::COUNTER << "th cookie";
-//
-// All "debug mode" logging is compiled away to nothing for non-debug mode
-// compiles.
-//
-// We also have
-//
-//   LOG_ASSERT(assertion);
-//   DLOG_ASSERT(assertion);
-//
-// which is syntactic sugar for {,D}LOG_IF(FATAL, assert fails) << assertion;
-//
-// There are "verbose level" logging macros.  They look like
-//
-//   VLOG(1) << "I'm printed when you run the program with --v=1 or more";
-//   VLOG(2) << "I'm printed when you run the program with --v=2 or more";
-//
-// These always log at the INFO log level (when they log at all).
-// The verbose logging can also be turned on module-by-module.  For instance,
-//    --vmodule=mapreduce=2,file=1,gfs*=3 --v=0
-// will cause:
-//   a. VLOG(2) and lower messages to be printed from mapreduce.{h,cc}
-//   b. VLOG(1) and lower messages to be printed from file.{h,cc}
-//   c. VLOG(3) and lower messages to be printed from files prefixed with "gfs"
-//   d. VLOG(0) and lower messages to be printed from elsewhere
-//
-// The wildcarding functionality shown by (c) supports both '*' (match
-// 0 or more characters) and '?' (match any single character) wildcards.
-//
-// There's also VLOG_IS_ON(n) "verbose level" condition macro. To be used as
-//
-//   if (VLOG_IS_ON(2)) {
-//     // do some logging preparation and logging
-//     // that can't be accomplished with just VLOG(2) << ...;
-//   }
-//
-// There are also VLOG_IF, VLOG_EVERY_N and VLOG_IF_EVERY_N "verbose level"
-// condition macros for sample cases, when some extra computation and
-// preparation for logs is not needed.
-//   VLOG_IF(1, (size > 1024))
-//      << "I'm printed when size is more than 1024 and when you run the "
-//         "program with --v=1 or more";
-//   VLOG_EVERY_N(1, 10)
-//      << "I'm printed every 10th occurrence, and when you run the program "
-//         "with --v=1 or more. Present occurence is " << google::COUNTER;
-//   VLOG_IF_EVERY_N(1, (size > 1024), 10)
-//      << "I'm printed on every 10th occurence of case when size is more "
-//         " than 1024, when you run the program with --v=1 or more. ";
-//         "Present occurence is " << google::COUNTER;
-//
-// The supported severity levels for macros that allow you to specify one
-// are (in increasing order of severity) INFO, WARNING, ERROR, and FATAL.
-// Note that messages of a given severity are logged not only in the
-// logfile for that severity, but also in all logfiles of lower severity.
-// E.g., a message of severity FATAL will be logged to the logfiles of
-// severity FATAL, ERROR, WARNING, and INFO.
-//
-// There is also the special severity of DFATAL, which logs FATAL in
-// debug mode, ERROR in normal mode.
-//
-// Very important: logging a message at the FATAL severity level causes
-// the program to terminate (after the message is logged).
-//
-// Unless otherwise specified, logs will be written to the filename
-// "<program name>.<hostname>.<user name>.log.<severity level>.", followed
-// by the date, time, and pid (you can't prevent the date, time, and pid
-// from being in the filename).
-//
-// The logging code takes two flags:
-//     --v=#           set the verbose level
-//     --logtostderr   log all the messages to stderr instead of to logfiles
-
-// LOG LINE PREFIX FORMAT
-//
-// Log lines have this form:
-//
-//     Lyyyymmdd hh:mm:ss.uuuuuu threadid file:line] msg...
-//
-// where the fields are defined as follows:
-//
-//   L                A single character, representing the log level
-//                    (eg 'I' for INFO)
-//   yyyy             The year
-//   mm               The month (zero padded; ie May is '05')
-//   dd               The day (zero padded)
-//   hh:mm:ss.uuuuuu  Time in hours, minutes and fractional seconds
-//   threadid         The space-padded thread ID as returned by GetTID()
-//                    (this matches the PID on Linux)
-//   file             The file name
-//   line             The line number
-//   msg              The user-supplied message
-//
-// Example:
-//
-//   I1103 11:57:31.739339 24395 google.cc:2341] Command line: ./some_prog
-//   I1103 11:57:31.739403 24395 google.cc:2342] Process id 24395
-//
-// NOTE: although the microseconds are useful for comparing events on
-// a single machine, clocks on different machines may not be well
-// synchronized.  Hence, use caution when comparing the low bits of

-// Note that this is technically undefined behavior! We are adding things into

-// operator overloads cannot be found via ADL. If these definitions are not
-// found via ADL, they must be #included before they're used, which requires
-// this header to be included before apparently independent other headers.
-//
-// For example, base/logging.h defines various template functions to implement
-// CHECK_EQ(x, y) and stream x and y into the log in the event the check fails.
-// It does so via the function template MakeCheckOpValueString:
-//   template<class T>
-//   void MakeCheckOpValueString(strstream* ss, const T& v) {
-//     (*ss) << v;
-//   }
-// Because 'glog/logging.h' is included before 'glog/stl_logging.h',
-// subsequent CHECK_EQ(v1, v2) for vector<...> typed variable v1 and v2 can only
-// find these operator definitions via ADL.
-//
-// Even this solution has problems -- it may pull unintended operators into the
-// namespace as well, allowing them to also be found via ADL, and creating code
-// that only works with a particular order of includes. Long term, we need to
-// move all of the *definitions* into namespace std, bet we need to ensure no
-// one references them first. This lets us take that step. We cannot define them
-// in both because that would create ambiguous overloads when both are found.

-// Defines the VLOG_IS_ON macro that controls the variable-verbosity
-// conditional logging.
-//
-// It's used by VLOG and VLOG_IF in logging.h
-// and by RAW_VLOG in raw_logging.h to trigger the logging.
-//
-// It can also be used directly e.g. like this:
-//   if (VLOG_IS_ON(2)) {
-//     // do some logging preparation and logging
-//     // that can't be accomplished e.g. via just VLOG(2) << ...;
-//   }
-//
-// The truth value that VLOG_IS_ON(level) returns is determined by 
-// the three verbosity level flags:
-//   --v=<n>  Gives the default maximal active V-logging level;
-//            0 is the default.
-//            Normally positive values are used for V-logging levels.
-//   --vmodule=<str>  Gives the per-module maximal V-logging levels to override
-//                    the value given by --v.
-//                    E.g. "my_module=2,foo*=3" would change the logging level
-//                    for all code in source files "my_module.*" and "foo*.*"
-//                    ("-inl" suffixes are also disregarded for this matching).
-//
-// SetVLOGLevel helper function is provided to do limited dynamic control over
-// V-logging by overriding the per-module settings given via --vmodule flag.
-//
-// CAVEAT: --vmodule functionality is not available in non gcc compilers.
