+// 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;

+// 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
+//
+// 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.

+// --vmodule=<str> Gives the per-module maximal V-logging levels to override
