-// 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.
