+This repository contains a C++ implementation of the Google logging
+module.  Documentation for the implementation is in doc/.
+
+See INSTALL for (generic) installation instructions for C++: basically
+    cd ./glog-0.3.3
+   ./configure && make && make install
+
+For RTOS 32 bit:
+    cd ./glog-0.3.3
+   ./configure CXXFLAGS=-m32 && make && make install
+
+Or, you can use automatic script:
+    sh build_for_ci.sh
+
+and you can collect the latest lib & includes:
+    sh collect.sh
+
+you can find them in glog/lib & glog/include, moreover path then to glog.tar.gz
+
+Add feature:
+    1. Support custom log, header file reference: nstack_glog_in.h;
+    2. Provide a C interface to invoke, header file reference: nstack_glog.ph;
+    3. Add the Debug level Release version, actually same to the INFO format log;
+    4. Provide dynamically print ,adjust the log level, use  NSTACK_LOG_LEVEL_ENABLE=[DEBUG/INFO/WARNING/ERROR/FATAL] , and first need use glogInit(char *param) and glogLevelSet(int logLevel)default is INFO level.
+    5. Fix bug: twice Init & shutdown.

+Glog-Specific Install Notes
+================================
+
+*** NOTE FOR 64-BIT LINUX SYSTEMS
+
+The glibc built-in stack-unwinder on 64-bit systems has some problems
+with the glog libraries.  (In particular, if you are using
+InstallFailureSignalHandler(), the signal may be raised in the middle
+of malloc, holding some malloc-related locks when they invoke the
+stack unwinder.  The built-in stack unwinder may call malloc
+recursively, which may require the thread to acquire a lock it already
+holds: deadlock.)
+
+For that reason, if you use a 64-bit system and you need
+InstallFailureSignalHandler(), we strongly recommend you install
+libunwind before trying to configure or install google glog.
+libunwind can be found at
+
+   http://download.savannah.nongnu.org/releases/libunwind/libunwind-snap-070410.tar.gz
+
+Even if you already have libunwind installed, you will probably still
+need to install from the snapshot to get the latest version.
+
+CAUTION: if you install libunwind from the URL above, be aware that
+you may have trouble if you try to statically link your binary with
+glog: that is, if you link with 'gcc -static -lgcc_eh ...'.  This
+is because both libunwind and libgcc implement the same C++ exception
+handling APIs, but they implement them differently on some platforms.
+This is not likely to be a problem on ia64, but may be on x86-64.
+
+Also, if you link binaries statically, make sure that you add
+-Wl,--eh-frame-hdr to your linker options. This is required so that
+libunwind can find the information generated by the compiler required
+for stack unwinding.
+
+Using -static is rare, though, so unless you know this will affect you
+it probably won't.
+
+If you cannot or do not wish to install libunwind, you can still try
+to use two kinds of stack-unwinder: 1. glibc built-in stack-unwinder
+and 2. frame pointer based stack-unwinder.
+
+1. As we already mentioned, glibc's unwinder has a deadlock issue.
+However, if you don't use InstallFailureSignalHandler() or you don't
+worry about the rare possibilities of deadlocks, you can use this
+stack-unwinder.  If you specify no options and libunwind isn't
+detected on your system, the configure script chooses this unwinder by
+default.
+
+2. The frame pointer based stack unwinder requires that your
+application, the glog library, and system libraries like libc, all be
+compiled with a frame pointer.  This is *not* the default for x86-64.
+
+If you are on x86-64 system, know that you have a set of system
+libraries with frame-pointers enabled, and compile all your
+applications with -fno-omit-frame-pointer, then you can enable the
+frame pointer based stack unwinder by passing the
+--enable-frame-pointers flag to configure.
+
+
+Basic Installation
+==================
+
+Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package.  The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.
+
+     Running `configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  6. Often, you can also type `make uninstall' to remove the installed
+     files again.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about.  Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug.  Until the bug is fixed you can use this workaround:
+
+     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+     Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+This project has begun being ported to Windows.  A working solution
+file exists in this directory:
+    google-glog.sln
+
+You can load this solution file into VC++ 9.0 (Visual Studio
+2008).  You may also be able to use this solution file with older
+Visual Studios by converting the solution file.
+
+Note that stack tracing and some unittests are not ported
+yet.
+
+You can also link glog code in statically -- see the example project
+libglog_static and logging_unittest_static, which does this.  For this
+to work, you'll need to add "/D GOOGLE_GLOG_DLL_DECL=" to the compile
+line of every glog's .cc file.
+
+I have little experience with Windows programming, so there may be
+better ways to set this up than I've done!  If you run across any
+problems, please post to the google-glog Google Group, or report
+them on the google-glog Google Code site:
+   http://groups.google.com/group/google-glog

+
+<h2> <A NAME=intro>Introduction</A> </h2>
+
+<p><b>Google glog</b> is a library that implements application-level
+logging.  This library provides logging APIs based on C++-style
+streams and various helper macros.
+You can log a message by simply streaming things to LOG(&lt;a
+particular <a href="#severity">severity level</a>&gt;), e.g.
+
+<pre>
+   #include &lt;glog/logging.h&gt;
+
+   int main(int argc, char* argv[]) {
+     // Initialize Google's logging library.
+     google::InitGoogleLogging(argv[0]);
+
+     // ...
+     LOG(INFO) &lt;&lt; "Found " &lt;&lt; num_cookies &lt;&lt; " cookies";
+   }
+</pre>
+
+<p>Google glog defines a series of macros that simplify many common logging
+tasks.  You can log messages by severity level, control logging
+behavior from the command line, log based on conditionals, abort the
+program when expected conditions are not met, introduce your own
+verbose logging levels, and more.  This document describes the
+functionality supported by glog.  Please note that this document
+doesn't describe all features in this library, but the most useful
+ones.  If you want to find less common features, please check
+header files under <code>src/glog</code> directory.
+
+<h2> <A NAME=severity>Severity Level</A> </h2>
+
+<p>
+You can specify one of the following severity levels (in
+increasing order of severity): <code>INFO</code>, <code>WARNING</code>,
+<code>ERROR</code>, and <code>FATAL</code>.
+Logging a <code>FATAL</code> message terminates the program (after the
+message is logged).
+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 <code>FATAL</code> will be logged to the
+logfiles of severity <code>FATAL</code>, <code>ERROR</code>,
+<code>WARNING</code>, and <code>INFO</code>.
+
+<p>
+The <code>DFATAL</code> severity logs a <code>FATAL</code> error in
+debug mode (i.e., there is no <code>NDEBUG</code> macro defined), but
+avoids halting the program in production by automatically reducing the
+severity to <code>ERROR</code>.
+
+<p>Unless otherwise specified, glog writes to the filename
+"/tmp/&lt;program name&gt;.&lt;hostname&gt;.&lt;user name&gt;.log.&lt;severity level&gt;.&lt;date&gt;.&lt;time&gt;.&lt;pid&gt;"
+(e.g., "/tmp/hello_world.example.com.hamaji.log.INFO.20080709-222411.10474").
+By default, glog copies the log messages of severity level
+<code>ERROR</code> or <code>FATAL</code> to standard error (stderr)
+in addition to log files.
+
+<h2><A NAME=flags>Setting Flags</A></h2>
+
+<p>Several flags influence glog's output behavior.
+If the <a href="http://code.google.com/p/google-gflags/">Google
+gflags library</a> is installed on your machine, the
+<code>configure</code> script (see the INSTALL file in the package for
+detail of this script) will automatically detect and use it,
+allowing you to pass flags on the command line.  For example, if you
+want to turn the flag <code>--logtostderr</code> on, you can start
+your application with the following command line:
+
+<pre>
+   ./your_application --logtostderr=1
+</pre>
+
+If the Google gflags library isn't installed, you set flags via
+environment variables, prefixing the flag name with "GLOG_", e.g.
+
+<pre>
+   GLOG_logtostderr=1 ./your_application
+</pre>
+
+<!-- TODO(hamaji): Fill the version number
+<p>By glog version 0.x.x, you can use GLOG_* environment variables
+even if you have gflags. If both an environment variable and a flag
+are specified, the value specified by a flag wins. E.g., if GLOG_v=0
+and --v=1, the verbosity will be 1, not 0.
+-->
+
+<p>The following flags are most commonly used:
+
+<dl>
+<dt><code>logtostderr</code> (<code>bool</code>, default=<code>false</code>)
+<dd>Log messages to stderr instead of logfiles.<br>
+Note: you can set binary flags to <code>true</code> by specifying
+<code>1</code>, <code>true</code>, or <code>yes</code> (case
+insensitive).
+Also, you can set binary flags to <code>false</code> by specifying
+<code>0</code>, <code>false</code>, or <code>no</code> (again, case
+insensitive).
+<dt><code>stderrthreshold</code> (<code>int</code>, default=2, which
+is <code>ERROR</code>)
+<dd>Copy log messages at or above this level to stderr in
+addition to logfiles.  The numbers of severity levels
+<code>INFO</code>, <code>WARNING</code>, <code>ERROR</code>, and
+<code>FATAL</code> are 0, 1, 2, and 3, respectively.
+<dt><code>minloglevel</code> (<code>int</code>, default=0, which
+is <code>INFO</code>)
+<dd>Log messages at or above this level.  Again, the numbers of
+severity levels <code>INFO</code>, <code>WARNING</code>,
+<code>ERROR</code>, and <code>FATAL</code> are 0, 1, 2, and 3,
+respectively.
+<dt><code>log_dir</code> (<code>string</code>, default="")
+<dd>If specified, logfiles are written into this directory instead
+of the default logging directory.
+<dt><code>v</code> (<code>int</code>, default=0)
+<dd>Show all <code>VLOG(m)</code> messages for <code>m</code> less or
+equal the value of this flag.  Overridable by --vmodule.
+See <a href="#verbose">the section about verbose logging</a> for more
+detail.
+<dt><code>vmodule</code> (<code>string</code>, default="")
+<dd>Per-module verbose level.  The argument has to contain a
+comma-separated list of &lt;module name&gt;=&lt;log level&gt;.
+&lt;module name&gt;
+is a glob pattern (e.g., <code>gfs*</code> for all modules whose name
+starts with "gfs"), matched against the filename base
+(that is, name ignoring .cc/.h./-inl.h).
+&lt;log level&gt; overrides any value given by --v.
+See also <a href="#verbose">the section about verbose logging</a>.
+</dl>
+
+<p>There are some other flags defined in logging.cc.  Please grep the
+source code for "DEFINE_" to see a complete list of all flags.
+
+<p>You can also modify flag values in your program by modifying global
+variables <code>FLAGS_*</code> . Most settings start working
+immediately after you update <code>FLAGS_*</code> . The exceptions are
+the flags related to destination files. For example, you might want to
+set <code>FLAGS_log_dir</code> before
+calling <code>google::InitGoogleLogging</code> . Here is an example:
+
+<pre>
+   LOG(INFO) << "file";
+   // Most flags work immediately after updating values.
+   FLAGS_logtostderr = 1;
+   LOG(INFO) << "stderr";
+   FLAGS_logtostderr = 0;
+   // This won't change the log destination. If you want to set this
+   // value, you should do this before google::InitGoogleLogging .
+   FLAGS_log_dir = "/some/log/directory";
+   LOG(INFO) << "the same file";
+</pre>
+
+<h2><A NAME=conditional>Conditional / Occasional Logging</A></h2>
+
+<p>Sometimes, you may only want to log a message under certain
+conditions. You can use the following macros to perform conditional
+logging:
+
+<pre>
+   LOG_IF(INFO, num_cookies &gt; 10) &lt;&lt; "Got lots of cookies";
+</pre>
+
+The "Got lots of cookies" message is logged only when the variable
+<code>num_cookies</code> exceeds 10.
+
+If a line of code is executed many times, it may be useful to only log
+a message at certain intervals.  This kind of logging is most useful
+for informational messages.
+
+<pre>
+   LOG_EVERY_N(INFO, 10) &lt;&lt; "Got the " &lt;&lt; google::COUNTER &lt;&lt; "th cookie";
+</pre>
+
+<p>The above line outputs a log messages on the 1st, 11th,
+21st, ... times it is executed.  Note that the special
+<code>google::COUNTER</code> value is used to identify which repetition is
+happening.
+
+<p>You can combine conditional and occasional logging with the
+following macro.
+
+<pre>
+   LOG_IF_EVERY_N(INFO, (size &gt; 1024), 10) &lt;&lt; "Got the " &lt;&lt; google::COUNTER
+                                           &lt;&lt; "th big cookie";
+</pre>
+
+<p>Instead of outputting a message every nth time, you can also limit
+the output to the first n occurrences:
+
+<pre>
+   LOG_FIRST_N(INFO, 20) &lt;&lt; "Got the " &lt;&lt; google::COUNTER &lt;&lt; "th cookie";
+</pre>
+
+<p>Outputs log messages for the first 20 times it is executed.  Again,
+the <code>google::COUNTER</code> identifier indicates which repetition is
+happening.
+
+<h2><A NAME=debug>Debug Mode Support</A></h2>
+
+<p>Special "debug mode" logging macros only have an effect in debug
+mode and are compiled away to nothing for non-debug mode
+compiles.  Use these macros to avoid slowing down your production
+application due to excessive logging.
+
+<pre>
+   DLOG(INFO) &lt;&lt; "Found cookies";
+
+   DLOG_IF(INFO, num_cookies &gt; 10) &lt;&lt; "Got lots of cookies";
+
+   DLOG_EVERY_N(INFO, 10) &lt;&lt; "Got the " &lt;&lt; google::COUNTER &lt;&lt; "th cookie";
+</pre>
+
+<h2><A NAME=check>CHECK Macros</A></h2>
+
+<p>It is a good practice to check expected conditions in your program
+frequently to detect errors as early as possible. The
+<code>CHECK</code> macro provides the ability to abort the application
+when a condition is not met, similar to the <code>assert</code> macro
+defined in the standard C library.
+
+<p><code>CHECK</code> aborts the application if a condition is not
+true.  Unlike <code>assert</code>, it is *not* controlled by
+<code>NDEBUG</code>, so the check will be executed regardless of
+compilation mode.  Therefore, <code>fp-&gt;Write(x)</code> in the
+following example is always executed:
+
+<pre>
+   CHECK(fp-&gt;Write(x) == 4) &lt;&lt; "Write failed!";
+</pre>
+
+<p>There are various helper macros for
+equality/inequality checks - <code>CHECK_EQ</code>,
+<code>CHECK_NE</code>, <code>CHECK_LE</code>, <code>CHECK_LT</code>,
+<code>CHECK_GE</code>, and <code>CHECK_GT</code>.
+They compare two values, and log a
+<code>FATAL</code> message including the two values when the result is
+not as expected.  The values must have <code>operator&lt;&lt;(ostream,
+...)</code> defined.
+
+<p>You may append to the error message like so:
+
+<pre>
+   CHECK_NE(1, 2) &lt;&lt; ": The world must be ending!";
+</pre>
+
+<p>We are very careful to ensure that each argument is evaluated exactly
+once, and that anything which is legal to pass as a function argument is
+legal here.  In particular, the arguments may be temporary expressions
+which will end up being destroyed at the end of the apparent statement,
+for example:
+
+<pre>
+   CHECK_EQ(string("abc")[1], 'b');
+</pre>
+
+<p>The compiler reports an error if one of the arguments is a
+pointer and the other is NULL. To work around this, simply static_cast
+NULL to the type of the desired pointer.
+
+<pre>
+   CHECK_EQ(some_ptr, static_cast&lt;SomeType*&gt;(NULL));
+</pre>
+
+<p>Better yet, use the CHECK_NOTNULL macro:
+
+<pre>
+   CHECK_NOTNULL(some_ptr);
+   some_ptr-&gt;DoSomething();
+</pre>
+
+<p>Since this macro returns the given pointer, this is very useful in
+constructor initializer lists.
+
+<pre>
+   struct S {
+     S(Something* ptr) : ptr_(CHECK_NOTNULL(ptr)) {}
+     Something* ptr_;
+   };
+</pre>
+
+<p>Note that you cannot use this macro as a C++ stream due to this
+feature.  Please use <code>CHECK_EQ</code> described above to log a
+custom message before aborting the application.
+
+<p>If you are comparing C strings (char *), a handy set of macros
+performs case sensitive as well as case insensitive comparisons -
+<code>CHECK_STREQ</code>, <code>CHECK_STRNE</code>,
+<code>CHECK_STRCASEEQ</code>, and <code>CHECK_STRCASENE</code>.  The
+CASE versions are case-insensitive.  You can safely pass <code>NULL</code>
+pointers for this macro.  They treat <code>NULL</code> and any
+non-<code>NULL</code> string as not equal.  Two <code>NULL</code>s are
+equal.
+
+<p>Note that both arguments may be temporary strings which are
+destructed at the end of the current "full expression"
+(e.g., <code>CHECK_STREQ(Foo().c_str(), Bar().c_str())</code> where
+<code>Foo</code> and <code>Bar</code> return C++'s
+<code>std::string</code>).
+
+<p>The <code>CHECK_DOUBLE_EQ</code> macro checks the equality of two
+floating point values, accepting a small error margin.
+<code>CHECK_NEAR</code> accepts a third floating point argument, which
+specifies the acceptable error margin.
+
+<h2><A NAME=verbose>Verbose Logging</A></h2>
+
+<p>When you are chasing difficult bugs, thorough log messages are very
+useful.  However, you may want to ignore too verbose messages in usual
+development.  For such verbose logging, glog provides the
+<code>VLOG</code> macro, which allows you to define your own numeric
+logging levels.  The <code>--v</code> command line option controls
+which verbose messages are logged:
+
+<pre>
+   VLOG(1) &lt;&lt; "I'm printed when you run the program with --v=1 or higher";
+   VLOG(2) &lt;&lt; "I'm printed when you run the program with --v=2 or higher";
+</pre>
+
+<p>With <code>VLOG</code>, the lower the verbose level, the more
+likely messages are to be logged.  For example, if
+<code>--v==1</code>, <code>VLOG(1)</code> will log, but
+<code>VLOG(2)</code> will not log.  This is opposite of the severity
+level, where <code>INFO</code> is 0, and <code>ERROR</code> is 2.
+<code>--minloglevel</code> of 1 will log <code>WARNING</code> and
+above.  Though you can specify any integers for both <code>VLOG</code>
+macro and <code>--v</code> flag, the common values for them are small
+positive integers.  For example, if you write <code>VLOG(0)</code>,
+you should specify <code>--v=-1</code> or lower to silence it.  This
+is less useful since we may not want verbose logs by default in most
+cases.  The <code>VLOG</code> macros always log at the
+<code>INFO</code> log level (when they log at all).
+
+<p>Verbose logging can be controlled from the command line on a
+per-module basis:
+
+<pre>
+   --vmodule=mapreduce=2,file=1,gfs*=3 --v=0
+</pre>
+
+<p>will:
+
+<ul>
+  <li>a. Print VLOG(2) and lower messages from mapreduce.{h,cc}
+  <li>b. Print VLOG(1) and lower messages from file.{h,cc}
+  <li>c. Print VLOG(3) and lower messages from files prefixed with "gfs"
+  <li>d. Print VLOG(0) and lower messages from elsewhere
+</ul>
+
+<p>The wildcarding functionality shown by (c) supports both '*'
+(matches 0 or more characters) and '?' (matches any single character)
+wildcards.  Please also check the section about <a
+href="#flags">command line flags</a>.
+
+<p>There's also <code>VLOG_IS_ON(n)</code> "verbose level" condition
+macro.  This macro returns true when the <code>--v</code> is equal or
+greater than <code>n</code>.  To be used as
+
+<pre>
+   if (VLOG_IS_ON(2)) {
+     // do some logging preparation and logging
+     // that can't be accomplished with just VLOG(2) &lt;&lt; ...;
+   }
+</pre>
+
+<p>Verbose level condition macros <code>VLOG_IF</code>,
+<code>VLOG_EVERY_N</code> and <code>VLOG_IF_EVERY_N</code> behave
+analogous to <code>LOG_IF</code>, <code>LOG_EVERY_N</code>,
+<code>LOF_IF_EVERY</code>, but accept a numeric verbosity level as
+opposed to a severity level.
+
+<pre>
+   VLOG_IF(1, (size &gt; 1024))
+      &lt;&lt; "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)
+      &lt;&lt; "I'm printed every 10th occurrence, and when you run the program "
+         "with --v=1 or more. Present occurence is " &lt;&lt; google::COUNTER;
+   VLOG_IF_EVERY_N(1, (size &gt; 1024), 10)
+      &lt;&lt; "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 " &lt;&lt; google::COUNTER;
+</pre>
+
+<h2> <A name="signal">Failure Signal Handler</A> </h2>
+
+<p>
+The library provides a convenient signal handler that will dump useful
+information when the program crashes on certain signals such as SIGSEGV.
+The signal handler can be installed by
+google::InstallFailureSignalHandler().  The following is an example of output
+from the signal handler.
+
+<pre>
+*** Aborted at 1225095260 (unix time) try "date -d @1225095260" if you are using GNU date ***
+*** SIGSEGV (@0x0) received by PID 17711 (TID 0x7f893090a6f0) from PID 0; stack trace: ***
+PC: @           0x412eb1 TestWaitingLogSink::send()
+    @     0x7f892fb417d0 (unknown)
+    @           0x412eb1 TestWaitingLogSink::send()
+    @     0x7f89304f7f06 google::LogMessage::SendToLog()
+    @     0x7f89304f35af google::LogMessage::Flush()
+    @     0x7f89304f3739 google::LogMessage::~LogMessage()
+    @           0x408cf4 TestLogSinkWaitTillSent()
+    @           0x4115de main
+    @     0x7f892f7ef1c4 (unknown)
+    @           0x4046f9 (unknown)
+</pre>
+
+<p>
+By default, the signal handler writes the failure dump to the standard
+error.  You can customize the destination by InstallFailureWriter().
+
+<h2> <A name="misc">Miscellaneous Notes</A> </h2>
+
+<h3><A NAME=message>Performance of Messages</A></h3>
+
+<p>The conditional logging macros provided by glog (e.g.,
+<code>CHECK</code>, <code>LOG_IF</code>, <code>VLOG</code>, ...) are
+carefully implemented and don't execute the right hand side
+expressions when the conditions are false.  So, the following check
+may not sacrifice the performance of your application.
+
+<pre>
+   CHECK(obj.ok) &lt;&lt; obj.CreatePrettyFormattedStringButVerySlow();
+</pre>
+
+<h3><A NAME=failure>User-defined Failure Function</A></h3>
+
+<p><code>FATAL</code> severity level messages or unsatisfied
+<code>CHECK</code> condition terminate your program.  You can change
+the behavior of the termination by
+<code>InstallFailureFunction</code>.
+
+<pre>
+   void YourFailureFunction() {
+     // Reports something...
+     exit(1);
+   }
+
+   int main(int argc, char* argv[]) {
+     google::InstallFailureFunction(&amp;YourFailureFunction);
+   }
+</pre>
+
+<p>By default, glog tries to dump stacktrace and makes the program
+exit with status 1.  The stacktrace is produced only when you run the
+program on an architecture for which glog supports stack tracing (as
+of September 2008, glog supports stack tracing for x86 and x86_64).
+
+<h3><A NAME=raw>Raw Logging</A></h3>
+
+<p>The header file <code>&lt;glog/raw_logging.h&gt;</code> can be
+used for thread-safe logging, which does not allocate any memory or
+acquire any locks.  Therefore, the macros defined in this
+header file can be used by low-level memory allocation and
+synchronization code.
+Please check <code>src/glog/raw_logging.h.in</code> for detail.
+</p>
+
+<h3><A NAME=plog>Google Style perror()</A></h3>
+
+<p><code>PLOG()</code> and <code>PLOG_IF()</code> and
+<code>PCHECK()</code> behave exactly like their <code>LOG*</code> and
+<code>CHECK</code> equivalents with the addition that they append a
+description of the current state of errno to their output lines.
+E.g.
+
+<pre>
+   PCHECK(write(1, NULL, 2) &gt;= 0) &lt;&lt; "Write NULL failed";
+</pre>
+
+<p>This check fails with the following error message.
+
+<pre>
+   F0825 185142 test.cc:22] Check failed: write(1, NULL, 2) &gt;= 0 Write NULL failed: Bad address [14]
+</pre>
+
+<h3><A NAME=syslog>Syslog</A></h3>
+
+<p><code>SYSLOG</code>, <code>SYSLOG_IF</code>, and
+<code>SYSLOG_EVERY_N</code> macros are available.
+These log to syslog in addition to the normal logs.  Be aware that
+logging to syslog can drastically impact performance, especially if
+syslog is configured for remote logging!  Make sure you understand the
+implications of outputting to syslog before you use these macros. In
+general, it's wise to use these macros sparingly.
+
+<h3><A NAME=strip>Strip Logging Messages</A></h3>
+
+<p>Strings used in log messages can increase the size of your binary
+and present a privacy concern.  You can therefore instruct glog to
+remove all strings which fall below a certain severity level by using
+the GOOGLE_STRIP_LOG macro:
+
+<p>If your application has code like this:
+
+<pre>
+   #define GOOGLE_STRIP_LOG 1    // this must go before the #include!
+   #include &lt;glog/logging.h&gt;
+</pre>
+
+<p>The compiler will remove the log messages whose severities are less
+than the specified integer value.  Since
+<code>VLOG</code> logs at the severity level <code>INFO</code>
+(numeric value <code>0</code>),
+setting <code>GOOGLE_STRIP_LOG</code> to 1 or greater removes
+all log messages associated with <code>VLOG</code>s as well as
+<code>INFO</code> log statements.
+
+<h3><A NAME=windows>Notes for Windows users</A></h3>
+
+<p>Google glog defines a severity level <code>ERROR</code>, which is
+also defined in <code>windows.h</code> . You can make glog not define
+<code>INFO</code>, <code>WARNING</code>, <code>ERROR</code>,
+and <code>FATAL</code> by defining
+<code>GLOG_NO_ABBREVIATED_SEVERITIES</code> before
+including <code>glog/logging.h</code> . Even with this macro, you can
+still use the iostream like logging facilities:
+
+<pre>
+  #define GLOG_NO_ABBREVIATED_SEVERITIES
+  #include &lt;windows.h&gt;
+  #include &lt;glog/logging.h&gt;
+
+  // ...
+
+  LOG(ERROR) &lt;&lt; "This should work";
+  LOG_IF(ERROR, x &gt; y) &lt;&lt; "This should be also OK";
+</pre>
+
+<p>
+However, you cannot
+use <code>INFO</code>, <code>WARNING</code>, <code>ERROR</code>,
+and <code>FATAL</code> anymore for functions defined
+in <code>glog/logging.h</code> .
+
+<pre>
+  #define GLOG_NO_ABBREVIATED_SEVERITIES
+  #include &lt;windows.h&gt;
+  #include &lt;glog/logging.h&gt;
+
+  // ...
+
+  // This won't work.
+  // google::FlushLogFiles(google::ERROR);
+
+  // Use this instead.
+  google::FlushLogFiles(google::GLOG_ERROR);
+</pre>
+
+<p>
+If you don't need <code>ERROR</code> defined
+by <code>windows.h</code>, there are a couple of more workarounds
+which sometimes don't work:
+
+<ul>
+  <li>#define <code>WIN32_LEAN_AND_MEAN</code> or <code>NOGDI</code>
+      <strong>before</strong> you #include <code>windows.h</code> .
+  <li>#undef <code>ERROR</code> <strong>after</strong> you #include
+      <code>windows.h</code> .
+</ul>
+
+<p>See <a href="http://code.google.com/p/google-glog/issues/detail?id=33">
+this issue</a> for more detail.

+dnl @summary figure out how to build C programs using POSIX threads
+dnl
+dnl This macro figures out how to build C programs using POSIX threads.
+dnl It sets the PTHREAD_LIBS output variable to the threads library and
+dnl linker flags, and the PTHREAD_CFLAGS output variable to any special
+dnl C compiler flags that are needed. (The user can also force certain
+dnl compiler flags/libs to be tested by setting these environment
+dnl variables.)
+dnl
+dnl Also sets PTHREAD_CC to any special C compiler that is needed for
+dnl multi-threaded programs (defaults to the value of CC otherwise).
+dnl (This is necessary on AIX to use the special cc_r compiler alias.)
+dnl
+dnl NOTE: You are assumed to not only compile your program with these
+dnl flags, but also link it with them as well. e.g. you should link
+dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS

+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.

+// 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

+// 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

+// Implementation note: the following code is a straightforward

+// 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,

+// The supported severity levels for macros that allow you to specify one

+// 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

+// Very important: logging a message at the FATAL severity level causes

+//
+// 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

+//
+// 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.

+// 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

+// This library provides Symbolize() function that symbolizes program
+// counters to their corresponding symbol names on linux platforms.
+// 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.
+//
+//   2. Open the mapped file and find a regular symbol table inside.
+//   Iterate over symbols in the symbol table and look for the symbol
+//   containing the program counter.  If such a symbol is found,
+//   obtain the symbol name, and demangle the symbol if possible.
+//   If the symbol isn't found in the regular symbol table (binary is
+//   stripped), try the same thing with a dynamic symbol table.
+//
+// Note that Symbolize() is originally implemented to be used in
+// FailureSignalHandler() in base/google.cc.  Hence it doesn't use
+// malloc() and other unsafe operations.  It should be both
+// thread-safe and async-signal-safe.

+// 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
+//
+// 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.

+//
+// 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
