+// 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:
+//
+//     Lmmdd 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)
+//   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

+// 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:

+// 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.
