-Installation Instructions
-*************************
-
-Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005 Free
-Software Foundation, Inc.
-
-This file is free documentation; the Free Software Foundation gives
-unlimited permission to copy, distribute and modify it.
-
-Basic Installation
-==================
-
-These are generic installation instructions.
-
-   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 only 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.  If you're
-     using `csh' on an old version of System V, you might need to type
-     `sh ./configure' instead to prevent `csh' from trying to execute
-     `configure' itself.
-
-     Running `configure' takes awhile.  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.
-
-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=c89 CFLAGS=-O2 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 must use a version of `make' that
-supports the `VPATH' variable, such as 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 `..'.
-
-   If you have to use a `make' that does not support the `VPATH'
-variable, you have 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).  Here is a another example:
-
-     /bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
-configuration-related scripts to be executed by `/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.

-open-vcdiff is an encoder and decoder for the VCDIFF format, as described in
-RFC 3284 : The VCDIFF Generic Differencing and Compression Data Format
-(http://www.ietf.org/rfc/rfc3284.txt)
-A library with a simple API is included, as well as a command-line executable
-that can apply the encoder and decoder to source, target, and delta files.
-For further details, please refer to:
-http://code.google.com/p/open-vcdiff/wiki/HowToUseOpenVcdiff
-
-See INSTALL for (generic) installation instructions for C++: basically
-   ./configure && make && make install
-
-This should compile the unit tests as well as "vcdiff", a simple command-line
-utility to run the encoder and decoder.  Typical usage of vcdiff is as follows
-(the "<" and ">" are file redirect operations, not optional arguments):
-   vcdiff encode -dictionary file.dict < target_file > delta_file
-   vcdiff decode -dictionary file.dict < delta_file > target_file
-To see the command-line syntax of vcdiff, use "vcdiff --help" or just "vcdiff".
-
-To call the encoder from C++ code, assuming that dictionary, target, and delta
-are all std::string objects:

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-\`configure' configures open-vcdiff 0.1 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

-			  [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.

-  CPP         C preprocessor
-  CXX         C++ compiler command
-  CXXFLAGS    C++ compiler flags
-  CXXCPP      C++ preprocessor
-  F77         Fortran 77 compiler command
-  FFLAGS      Fortran 77 compiler flags
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.

-dnl @synopsis ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
-dnl
-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
-dnl $LIBS
-dnl
-dnl If you are only building threads programs, you may wish to use
-dnl these variables in your default LIBS, CFLAGS, and CC:
-dnl
-dnl        LIBS="$PTHREAD_LIBS $LIBS"
-dnl        CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
-dnl        CC="$PTHREAD_CC"
-dnl
-dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
-dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
-dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
-dnl
-dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
-dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to
-dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the
-dnl default action will define HAVE_PTHREAD.
-dnl
-dnl Please let the authors know if this macro fails on any platform, or
-dnl if you have any other suggestions or comments. This macro was based
-dnl on work by SGJ on autoconf scripts for FFTW (www.fftw.org) (with
-dnl help from M. Frigo), as well as ac_pthread and hb_pthread macros
-dnl posted by Alejandro Forero Cuervo to the autoconf macro repository.
-dnl We are also grateful for the helpful feedback of numerous users.

-//
-// Assumptions:
-//   * The VCDAddress type is large enough to hold any offset within
-//     the source and target windows.  The limit (for int32_t) is 2^31-1 bytes.
-//     The source (dictionary) should not approach this size limit;
-//     to compress a target file that is larger than
-//     INT_MAX - (dictionary size) bytes, the encoder must
-//     break it up into multiple target windows.

-//   same_cache_size: Size of the SAME cache (number of blocks of

-// Interprets the next value in the address_stream using the provided mode,

-//
-// Arguments:
-//   here_address: The current location in the source + target data (i.e., the
-//       location into which the COPY instruction will copy.)  By definition,
-//       all addresses between 0 and (here_address - 1) are valid, and
-//       any other address is invalid.
-//   mode: A byte value between 0 and (near_cache_size_ + same_cache_size_ + 1)
-//       which tells how to interpret the next value in the address stream.
-//       The values 0 and 1 correspond to SELF and HERE addressing.
-//       The validity of "mode" should already have been checked before
-//       calling this function.
-//   address_stream: Points to a pointer holding the position
-//       in the "Addresses section for COPYs" part of the input data.
-//       That section must already have been uncompressed
-//       using a secondary decompressor (if necessary.)
-//       This is an IN/OUT argument; the value of *address_stream will be
-//       incremented by the size of an integer, or (if the SAME cache
-//       was used) by the size of a byte (1).
-//   address_stream_end: Points to the position just after the end of
-//       the address stream buffer.  All addresses between *address_stream
-//       and address_stream_end should contain valid address data.
-//
-// Return value: If the input conditions were met, and the address section
-//     of the input data contains properly encoded addresses that match
-//     the instructions section, then an integer between 0 and here_address - 1
-//     will be returned, representing the address from which data should
-//     be copied from the source or target window into the output stream.
-//     If an invalid address value is found in address_stream, then
-//     RESULT_ERROR will be returned.  If the limit address_stream_end
-//     is reached before the address can be decoded, then
-//     RESULT_END_OF_DATA will be returned.  If more streamed data
-//     is expected, this means that the consumer should block and wait
-//     for more data before continuing to decode.  If no more data is expected,
-//     this return value signals an error condition.

-  //      starting_offset_ to any best_match->source_offset() value it returns,
-  //      in order to produce the correct offset value for a target BlockHash.
-  //   2. For a dictionary BlockHash, the entire data set is hashed at once
-  //      when Init() is called with the parameter populate_hash_table = true.
-  //      For a target BlockHash, because the previously encoded target data
-  //      includes only the data seen up to the current encoding position,
-  //      the data blocks are hashed incrementally as the encoding position

-// The COMPILE_ASSERT macro can be used to verify that a compile-time
-// expression is true. For example, you could use it to verify the
-// size of a static array:
-//
-//   COMPILE_ASSERT(ARRAYSIZE(content_type_names) == CONTENT_NUM_TYPES,
-//                  content_type_names_incorrect_size);
-//
-// or to make sure a struct is smaller than a certain size:
-//
-//   COMPILE_ASSERT(sizeof(foo) < 128, foo_too_large);
-//
-// For the second argument to COMPILE_ASSERT, the programmer should supply
-// a variable name that meets C++ naming rules, but that provides
-// a description of the compile-time rule that has been violated.
-// (In the example above, the name used is "foo_too_large".)
-// If the expression is false, most compilers will issue a warning/error
-// containing the name of the variable.
-// This refinement (adding a descriptive variable name argument)
-// is what differentiates COMPILE_ASSERT from Boost static asserts.
-
-template <bool>
-struct CompileAssert {
-};
-
-#define COMPILE_ASSERT(expr, msg) \
-  typedef CompileAssert<static_cast<bool>(expr)> \
-      msg[static_cast<bool>(expr) ? 1 : -1]
-
-// Implementation details of COMPILE_ASSERT:
-//
-// - COMPILE_ASSERT works by defining an array type that has -1
-//   elements (and thus is invalid) when the expression is false.
-//
-// - The simpler definition
-//
-//     #define COMPILE_ASSERT(expr, msg) typedef char msg[(expr) ? 1 : -1]
-//
-//   does not work, as gcc supports variable-length arrays whose sizes
-//   are determined at run-time (this is gcc's extension and not part
-//   of the C++ standard).  As a result, gcc fails to reject the
-//   following code with the simple definition:
-//
-//     int foo;
-//     COMPILE_ASSERT(foo, msg); // not supposed to compile as foo is
-//                               // not a compile-time constant.
-//
-// - By using the type CompileAssert<(static_cast<bool>(expr))>, we ensure that
-//   expr is a compile-time constant.  (Template arguments must be
-//   determined at compile-time.)
-//
-// - The array size is (static_cast<bool>(expr) ? 1 : -1), instead of simply
-//
-//     ((expr) ? 1 : -1).
-//
-//   This is to avoid running into a bug in MS VC 7.1, which
-//   causes ((0.0) ? 1 : -1) to incorrectly evaluate to 1.

-// The VCDiff format allows each opcode to represent either
-// one or two delta instructions.  This function will first
-// examine the opcode generated by the last call to EncodeInstruction.
-// If that opcode was a single-instruction opcode, this function checks
-// whether there is a compound (double-instruction) opcode that can
-// combine that single instruction with the instruction that is now
-// being added, and so save a byte of space.  In that case, the
-// single-instruction opcode at position last_opcode_index_ will be
-// overwritten with the new double-instruction opcode.
-//
-// In the majority of cases, no compound opcode will be possible,
-// and a new single-instruction opcode will be appended to
-// instructions_and_sizes_, followed by a representation of its size
-// if the opcode does not implicitly give the instruction size.
-//
-// As an example, say instructions_and_sizes_ contains 10 bytes, the last
-// of which contains the opcode 0x02 (ADD size 1).  Because that was the
-// most recently added opcode, last_opcode_index_ has the value 10.
-// EncodeInstruction is then called with inst = VCD_COPY, size = 4, mode = 0.
-// The function will replace the old opcode 0x02 with the double-instruction
-// opcode 0xA3 (ADD size 1 + COPY size 4 mode 0).
-//
-// All of the double-instruction opcodes in the standard code table
-// have implicit sizes, meaning that the size of the instruction will not
-// need to be written to the instructions_and_sizes_ string separately
-// from the opcode.  If a custom code table were used that did not have
-// this property, then instructions_and_sizes_ might contain a
-// double-instruction opcode (say, COPY size 0 mode 0 + ADD size 0)
-// followed by the size of the COPY, then by the size of the ADD.
-// If using the SDCH interleaved format, the address of the COPY instruction
-// would follow its size, so the ordering would be

-// Author: Ray Sidney
-// Revamped and reorganized by Craig Silverstein
-//
-// This file contains the implementation of all our command line flags
-// stuff.  Here's how everything fits together
-//
-// * FlagRegistry owns CommandLineFlags owns FlagValue.
-// * FlagSaver holds a FlagRegistry (saves it at construct time,
-//     restores it at destroy time).
-// * CommandLineFlagParser lives outside that hierarchy, but works on
-//     CommandLineFlags (modifying the FlagValues).
-// * Free functions like SetCommandLineOption() work via one of the
-//     above (such as CommandLineFlagParser).
-//
-// In more detail:
-//
-// -- The main classes that hold flag data:
-//
-// FlagValue holds the current value of a flag.  It's
-// pseudo-templatized: every operation on a FlagValue is typed.  It
-// also deals with storage-lifetime issues (so flag values don't go
-// away in a destructor), which is why we need a whole class to hold a
-// variable's value.
-//
-// CommandLineFlag is all the information about a single command-line
-// flag.  It has a FlagValue for the flag's current value, but also
-// the flag's name, type, etc.
-//
-// FlagRegistry is a collection of CommandLineFlags.  There's the
-// global registry, which is where flags defined via DEFINE_foo()
-// live.  But it's possible to define your own flag, manually, in a
-// different registry you create.  (In practice, multiple registries
-// are used only by FlagSaver).
-//
-// A given FlagValue is owned by exactly one CommandLineFlag.  A given
-// CommandLineFlag is owned by exactly one FlagRegistry.  FlagRegistry
-// has a lock; any operation that writes to a FlagValue or
-// CommandLineFlag owned by that registry must acquire the
-// FlagRegistry lock before doing so.
-//
-// --- Some other classes and free functions:
-//
-// CommandLineFlagInfo is a client-exposed version of CommandLineFlag.
-// Once it's instantiated, it has no dependencies or relationships
-// with any other part of this file.
-//
-// FlagRegisterer is the helper class used by the DEFINE_* macros to
-// allow work to be done at global initialization time.
-//
-// CommandLineFlagParser is the class that reads from the commandline
-// and instantiates flag values based on that.  It needs to poke into
-// the innards of the FlagValue->CommandLineFlag->FlagRegistry class
-// hierarchy to do that.  It's careful to acquire the FlagRegistry
-// lock before doing any writing or other non-const actions.
-//
-// GetCommandLineOption is just a hook into registry routines to
-// retrieve a flag based on its name.  SetCommandLineOption, on the
-// other hand, hooks into CommandLineFlagParser.  Other API functions
-// are, similarly, mostly hooks into the functionality described above.

-//    like arg we can't make sense of, we store it in a vector,
-//    along with an explanation of the trouble.  In stage 2, we
-//    handle the 'reporting' flags like --help and --mpm_version.

-//    gflags_reporting.cc.)
-//    An optional stage 3 prints out the error messages.
-//       This is a bit of a simplification.  For instance, --flagfile
-//    is handled as soon as it's seen in stage 1, not in stage 2.

-// declared in the main commandlineflags.h header file.
-//
-// HandleCommandLineHelpFlags() will check what 'reporting' flags have
-// been defined, if any -- the "help" part of the function name is a
-// bit misleading -- and do the relevant reporting.  It should be
-// called after all flag-values have been assigned, that is, after

-// thread-hostile: it is not safe for multiple threads to call this

-// thread-compatible: it is safe for multiple threads to read from
-//   this variable (when applied to variables), or to call const

-// Now come the command line flag declaration/definition macros that

-// variables in global constructors and have that not crash, even if
-// their global constructor runs before the global constructor here.
-// (Obviously, we can't guarantee the flags will have the correct
-// default value in that case, but at least accessing them is safe.)
-// The only way to do that is have flags point to a static buffer.
-// So we make one, using a union to ensure proper alignment, and
-// then use placement-new to actually set up the flag with the
-// correct default value.  In the same vein, we have to worry about
-// flag access in global destructors, so FlagRegisterer has to be
-// careful never to destroy the flag-values it constructs.
-//
-// Note that when we define a flag variable FLAGS_<name>, we also
-// preemptively define a junk variable, FLAGS_no<name>.  This is to
-// cause a link-time error if someone tries to define 2 flags with
-// names like "logging" and "nologging".  We do this because a bool
-// flag FLAG can be set from the command line to true with a "-FLAG"
-// argument, and to false with a "-noFLAG" argument, and so this can
-// potentially avert confusion.
-//
-// We also 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_whatever;"
-// 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.

-// people can't DECLARE_int32 something that they DEFINE_bool'd

-Google C++ Testing Framework
-============================
-http://code.google.com/p/googletest/
-
-Overview
---------
-Google's framework for writing C++ tests on a variety of platforms (Linux, Mac
-OS X, Windows, Windows CE, and Symbian). Based on the xUnit architecture.
-Supports automatic test discovery, a rich set of assertions, user-defined
-assertions, death tests, fatal and non-fatal failures, various options for
-running the tests, and XML test report generation.
-
-Please see the project page above for more information as well as mailing lists
-for questions, discussions, and development. There is also an IRC channel on
-OFTC (irc.oftc.net) #gtest available. Please join us!
-
-Requirements
-------------
-Google Test is designed to have fairly minimal requirements to build and use
-with your projects, but there are some. Currently, the only Operating System
-(OS) on which Google Test is known to build properly is Linux, but we are
-actively working on Windows and Mac support as well. The source code itself is
-already portable across many other platforms, but we are still developing
-robust build systems for each.
-
-### Linux Requirements ###
-These are the base requirements to build and use Google Test from a source
-package (as described below):
-  * GNU-compatible Make or "gmake"
-  * POSIX-standard shell
-  * POSIX(-2) Regular Expressions (regex.h)
-  * A C++98 standards compliant compiler
-
-Furthermore, if you are building Google Test from a VCS Checkout (also
-described below), there are further requirements:
-  * Automake version 1.9 or newer
-  * Autoconf version 2.59 or newer
-  * Libtool / Libtoolize
-  * Python version 2.4 or newer
-
-### Windows Requirements ###
-  * Microsoft Visual Studio 7.1 or newer
-
-### Cygwin Requirements ###
-  * Cygwin 1.5.25-14 or newer
-
-### Mac OS X Requirements ###
-  * Mac OS X 10.4 Tiger or newer
-
-Getting the Source
-------------------
-There are two primary ways of getting Google Test's source code: you can
-download a source release in your preferred archive format, or directly check
-out the source from a Version Control System (VCS, we use Google Code's
-Subversion hosting). The VCS checkout requires a few extra steps and some extra
-software packages on your system, but lets you track development, and make
-patches to contribute much more easily, so we highly encourage it.
-
-### VCS Checkout: ###
-The first step is to select whether you want to check out the main line of
-development on Google Test, or one of the released branches. The former will be
-much more active and have the latest features, but the latter provides much
-more stability and predictability. Choose whichever fits your needs best, and
-proceed with the following Subversion commands:
-
-  $ svn checkout http://googletest.googlecode.com/svn/trunk/ gtest-svn
-
-or for a release version X.Y.*'s branch:
-
-  $ svn checkout http://googletest.googlecode.com/svn/branches/release-X.Y/ gtest-X.Y-svn
-
-Next you will need to prepare the GNU Autotools build system, if you
-are using Linux, Mac OS X, or Cygwin. Enter the target directory of
-the checkout command you used ('gtest-svn' or 'gtest-X.Y-svn' above)
-and proceed with the following commands:
-
-  $ aclocal-1.9       # Where "1.9" must match the following automake command.
-  $ libtoolize -c     # Use "glibtoolize -c" instead on Mac OS X.
-  $ autoheader
-  $ automake-1.9 -ac  # See Automake version requirements above.
-  $ autoconf
-
-While this is a bit complicated, it will most often be automatically re-run by
-your "make" invocations, so in practice you shouldn't need to worry too much.
-Once you have completed these steps, you are ready to build the library. 
-
-### Source Package: ###
-Google Test is also released in source packages which can be downloaded from
-its Google Code download page[1]. Several different archive formats are
-provided, but the only difference is the tools used to manipulate them, and the
-size of the resulting file. Download whichever you are most comfortable with.
-
-  [1] Google Test Downloads: http://code.google.com/p/googletest/downloads/list
-
-Once downloaded expand the archive using whichever tools you prefer for that
-type. This will always result in a new directory with the name "gtest-X.Y.Z"
-which contains all of the source code. Here are some examples in Linux:
-
-  $ tar -xvzf gtest-X.Y.Z.tar.gz
-  $ tar -xvjf gtest-X.Y.Z.tar.bz2
-  $ unzip gtest-X.Y.Z.zip
-
-Building the Source
--------------------
-
-### Linux, Mac OS X, and Cygwin ###
-There are two primary options for building the source at this point: build it
-inside the source code tree, or in a separate directory. We recommend building
-in a separate directory as that tends to produce both more consistent results
-and be easier to clean up should anything go wrong, but both patterns are
-supported. The only hard restriction is that while the build directory can be
-a subdirectory of the source directory, the opposite is not possible and will
-result in errors. Once you have selected where you wish to build Google Test,
-create the directory if necessary, and enter it. The following steps apply for
-either approach by simply substituting the shell variable SRCDIR with "." for
-building inside the source directory, and the relative path to the source
-directory otherwise.
-
-  $ ${SRCDIR}/configure  # Standard GNU configure script, --help for more info
-  $ make  # Standard makefile following GNU conventions
-  $ make check  # Builds and runs all tests - all should pass
-
-Other programs will only be able to use Google Test's functionality if you
-install it in a location which they can access, in Linux this is typically
-under '/usr/local'. The following command will install all of the Google Test
-libraries, public headers, and utilities necessary for other programs and
-libraries to leverage it:
-
-  $ sudo make install  # Not necessary, but allows use by other programs
-
-TODO(chandlerc@google.com): This section needs to be expanded when the
-'gtest-config' script is finished and Autoconf macro's are provided (or not
-provided) in order to properly reflect the process for other programs to
-locate, include, and link against Google Test.
-
-Finally, should you need to remove Google Test from your system after having
-installed it, run the following command, and it will back out its changes.
-However, note carefully that you must run this command on the *same* Google
-Test build that you ran the install from, or the results are not predictable.
-If you install Google Test on your system, and are working from a VCS checkout,
-make sure you run this *before* updating your checkout of the source in order
-to uninstall the same version which you installed.
-
-  $ sudo make uninstall  # Must be run against the exact same build as "install"
-
-### Windows ###
-Open the gtest.sln file in the msvc/ folder using Visual Studio, and
-you are ready to build Google Test the same way you build any Visual
-Studio project.
-
-Happy testing!

-
-// The following macros are useful for writing death tests.
-
-// Here's what happens when an ASSERT_DEATH* or EXPECT_DEATH* is
-// executed:
-//
-//   1. The assertion fails immediately if there are more than one
-//   active threads.  This is because it's safe to fork() only when
-//   there is a single thread.
-//
-//   2. The parent process forks a sub-process and runs the death test
-//   in it; the sub-process exits with code 0 at the end of the death
-//   test, if it hasn't exited already.
-//
-//   3. The parent process waits for the sub-process to terminate.
-//
-//   4. The parent process checks the exit code and error message of
-//   the sub-process.
-//
-// Note:
-//
-// It's not safe to call exit() if the current process is forked from
-// a multi-threaded process, so people usually call _exit() instead in
-// such a case.  However, we are not concerned with this as we run
-// death tests only when there is a single thread.  Since exit() has a
-// cleaner semantics (it also calls functions registered with atexit()
-// and on_exit()), this macro calls exit() instead of _exit() to
-// terminate the child process.
-//
-// Examples:
-//
-//   ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number");
-//   for (int i = 0; i < 5; i++) {
-//     EXPECT_DEATH(server.ProcessRequest(i),
-//                  "Invalid request .* in ProcessRequest()")
-//         << "Failed to die on request " << i);
-//   }
-//
-//   ASSERT_EXIT(server.ExitNow(), ::testing::ExitedWithCode(0), "Exiting");
-//
-//   bool KilledBySIGHUP(int exit_code) {
-//     return WIFSIGNALED(exit_code) && WTERMSIG(exit_code) == SIGHUP;
-//   }
-//
-//   ASSERT_EXIT(client.HangUpServer(), KilledBySIGHUP, "Hanging up!");
-
-// Asserts that a given statement causes the program to exit, with an
-// integer exit status that satisfies predicate, and emitting error output
-// that matches regex.
-#define ASSERT_EXIT(statement, predicate, regex) \
-  GTEST_DEATH_TEST(statement, predicate, regex, GTEST_FATAL_FAILURE)
-
-// Like ASSERT_EXIT, but continues on to successive tests in the
-// test case, if any:
-#define EXPECT_EXIT(statement, predicate, regex) \
-  GTEST_DEATH_TEST(statement, predicate, regex, GTEST_NONFATAL_FAILURE)

-
-// EXPECT_DEBUG_DEATH asserts that the given statements die in debug mode.
-// The death testing framework causes this to have interesting semantics,
-// since the sideeffects of the call are only visible in opt mode, and not
-// in debug mode.
-//
-// In practice, this can be used to test functions that utilize the
-// LOG(DFATAL) macro using the following style:
-//
-// int DieInDebugOr12(int* sideeffect) {
-//   if (sideeffect) {
-//     *sideeffect = 12;
-//   }
-//   LOG(DFATAL) << "death";
-//   return 12;
-// }
-//
-// TEST(TestCase, TestDieOr12WorksInDgbAndOpt) {
-//   int sideeffect = 0;
-//   // Only asserts in dbg.
-//   EXPECT_DEBUG_DEATH(DieInDebugOr12(&sideeffect), "death");

-//   // opt-mode has sideeffect visible.
-//   EXPECT_EQ(12, sideeffect);
-// #else
-//   // dbg-mode no visible sideeffect.
-//   EXPECT_EQ(0, sideeffect);
-// #endif
-// }
-//
-// This will assert that DieInDebugReturn12InOpt() crashes in debug
-// mode, usually due to a DCHECK or LOG(DFATAL), but returns the
-// appropriate fallback value (12 in this case) in opt mode. If you
-// need to test that a function has appropriate side-effects in opt
-// mode, include assertions against the side-effects.  A general
-// pattern for this is:
-//
-// EXPECT_DEBUG_DEATH({
-//   // Side-effects here will have an effect after this statement in

-// The Message class works like an ostream repeater.
-//
-// Typical usage:
-//
-//   1. You stream a bunch of values to a Message object.
-//      It will remember the text in a StrStream.
-//   2. Then you stream the Message object to an ostream.
-//      This causes the text in the Message to be streamed
-//      to the ostream.
-//
-// For example;
-//
-//   testing::Message foo;
-//   foo << 1 << " != " << 2;
-//   std::cout << foo;
-//
-// will print "1 != 2".
-//
-// Message is not intended to be inherited from.  In particular, its
-// destructor is not virtual.
-//
-// Note that StrStream behaves differently in gcc and in MSVC.  You
-// can stream a NULL char pointer to it in the former, but not in the
-// latter (it causes an access violation if you do).  The Message
-// class hides this difference by treating a NULL char pointer as
-// "(null)".

-// Macros for indicating success/failure in test code.
-
-// ADD_FAILURE unconditionally adds a failure to the current test.
-// SUCCEED generates a success - it doesn't automatically make the
-// current test successful, as a test is only successful when it has
-// no failure.
-//
-// EXPECT_* verifies that a certain condition is satisfied.  If not,
-// it behaves like ADD_FAILURE.  In particular:
-//
-//   EXPECT_TRUE  verifies that a Boolean condition is true.
-//   EXPECT_FALSE verifies that a Boolean condition is false.
-//
-// FAIL and ASSERT_* are similar to ADD_FAILURE and EXPECT_*, except
-// that they will also abort the current function on failure.  People
-// usually want the fail-fast behavior of FAIL and ASSERT_*, but those
-// writing data-driven tests often find themselves using ADD_FAILURE
-// and EXPECT_* more.
-//
-// Examples:
-//
-//   EXPECT_TRUE(server.StatusIsOK());
-//   ASSERT_FALSE(server.HasPendingRequest(port))
-//       << "There are still pending requests " << "on port " << port;

-//
-// When they are not, Google Test prints both the tested expressions and
-// their actual values.  The values must be compatible built-in types,
-// or you will get a compiler error.  By "compatible" we mean that the
-// values can be compared by the respective operator.
-//
-// Note:
-//
-//   1. It is possible to make a user-defined type work with
-//   {ASSERT|EXPECT}_??(), but that requires overloading the
-//   comparison operators and is thus discouraged by the Google C++
-//   Usage Guide.  Therefore, you are advised to use the
-//   {ASSERT|EXPECT}_TRUE() macro to assert that two objects are
-//   equal.
-//
-//   2. The {ASSERT|EXPECT}_??() macros do pointer comparisons on
-//   pointers (in particular, C strings).  Therefore, if you use it
-//   with two C strings, you are testing how their locations in memory
-//   are related, not how their content is related.  To compare two C
-//   strings by content, use {ASSERT|EXPECT}_STR*().
-//
-//   3. {ASSERT|EXPECT}_EQ(expected, actual) is preferred to
-//   {ASSERT|EXPECT}_TRUE(expected == actual), as the former tells you
-//   what the actual value is when it fails, and similarly for the
-//   other comparisons.
-//
-//   4. Do not depend on the order in which {ASSERT|EXPECT}_??()
-//   evaluate their arguments, which is undefined.
-//
-//   5. These macros evaluate their arguments exactly once.
-//
-// Examples:
-//
-//   EXPECT_NE(5, Foo());
-//   EXPECT_EQ(NULL, a_pointer);
-//   ASSERT_LT(i, array_size);
-//   ASSERT_GT(records.size(), 0) << "There is no record left.";

-//
-// The implementation found in this file contains buffer bounds checks
-// (not available in sqlite) and its goal is to improve speed

-//
-// The Sqlite format has the refinement that, if a 64-bit value is expected,
-// the ninth byte of the varint does not have a continuation bit, but instead
-// encodes 8 bits of information.  This allows 64 bits to be encoded compactly
-// in nine bytes.  However, that refinement does not appear in the format
-// description in RFC 3284, and so it is not used here.  In any case,
-// this header file deals only with *signed* integer types, and so a
-// "64-bit" integer is allowed to have only 63 significant bits; an additional
-// 64th bit would indicate a negative value and therefore an error.

-     The 'zlib' compression library provides in-memory compression and
-  decompression functions, including integrity checks of the uncompressed
-  data.  This version of the library supports only one compression method
-  (deflation) but other algorithms will be added later and will have the same
-  stream interface.
-
-     Compression can be done in a single step if the buffers are large
-  enough (for example if an input file is mmap'ed), or can be done by
-  repeated calls of the compression function.  In the latter case, the
-  application must provide more input and/or consume the output
-  (providing more output space) before each call.
-
-     The compressed data format used by default by the in-memory functions is
-  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
-  around a deflate stream, which is itself documented in RFC 1951.
-
-     The library also supports reading and writing files in gzip (.gz) format
-  with an interface similar to that of stdio using the functions that start
-  with "gz".  The gzip format is different from the zlib format.  gzip is a
-  gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
-
-     This library can optionally read and write gzip streams in memory as well.
-
-     The zlib format was designed to be compact and fast for use in memory
-  and on communications channels.  The gzip format was designed for single-
-  file compression on file systems, has a larger header than zlib to maintain
-  directory information, and uses a different, slower check method than zlib.
-
-     The library does not install any signal handler. The decoder checks
-  the consistency of the compressed data, so the library should never
-  crash even in case of corrupted input.

-    deflate compresses as much data as possible, and stops when the input
-  buffer becomes empty or the output buffer becomes full. It may introduce some
-  output latency (reading input without producing any output) except when
-  forced to flush.
-
-    The detailed semantics are as follows. deflate performs one or both of the
-  following actions:
-
-  - Compress more input starting at next_in and update next_in and avail_in
-    accordingly. If not all input can be processed (because there is not
-    enough room in the output buffer), next_in and avail_in are updated and
-    processing will resume at this point for the next call of deflate().
-
-  - Provide more output starting at next_out and update next_out and avail_out
-    accordingly. This action is forced if the parameter flush is non zero.
-    Forcing flush frequently degrades the compression ratio, so this parameter
-    should be set only when necessary (in interactive applications).
-    Some output may be provided even if flush is not set.
-
-  Before the call of deflate(), the application should ensure that at least
-  one of the actions is possible, by providing more input and/or consuming
-  more output, and updating avail_in or avail_out accordingly; avail_out
-  should never be zero before the call. The application can consume the
-  compressed output when it wants, for example when the output buffer is full
-  (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
-  and with zero avail_out, it must be called again after making room in the
-  output buffer because there might be more output pending.
-
-    Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
-  decide how much data to accumualte before producing output, in order to
-  maximize compression.
-
-    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
-  flushed to the output buffer and the output is aligned on a byte boundary, so
-  that the decompressor can get all input data available so far. (In particular
-  avail_in is zero after the call if enough output space has been provided
-  before the call.)  Flushing may degrade compression for some compression
-  algorithms and so it should be used only when necessary.
-
-    If flush is set to Z_FULL_FLUSH, all output is flushed as with
-  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
-  restart from this point if previous compressed data has been damaged or if
-  random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
-  compression.
-
-    If deflate returns with avail_out == 0, this function must be called again
-  with the same value of the flush parameter and more output space (updated
-  avail_out), until the flush is complete (deflate returns with non-zero
-  avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
-  avail_out is greater than six to avoid repeated flush markers due to
-  avail_out == 0 on return.
-
-    If the parameter flush is set to Z_FINISH, pending input is processed,
-  pending output is flushed and deflate returns with Z_STREAM_END if there
-  was enough output space; if deflate returns with Z_OK, this function must be
-  called again with Z_FINISH and more output space (updated avail_out) but no
-  more input data, until it returns with Z_STREAM_END or an error. After
-  deflate has returned Z_STREAM_END, the only possible operations on the
-  stream are deflateReset or deflateEnd.
-
-    Z_FINISH can be used immediately after deflateInit if all the compression
-  is to be done in a single step. In this case, avail_out must be at least
-  the value returned by deflateBound (see below). If deflate does not return
-  Z_STREAM_END, then it must be called again as described above.
-
-    deflate() sets strm->adler to the adler32 checksum of all input read
-  so far (that is, total_in bytes).
-
-    deflate() may update strm->data_type if it can make a good guess about
-  the input data type (Z_BINARY or Z_TEXT). In doubt, the data is considered
-  binary. This field is only for information purposes and does not affect
-  the compression algorithm in any manner.
-
-    deflate() returns Z_OK if some progress has been made (more input
-  processed or more output produced), Z_STREAM_END if all input has been
-  consumed and all output has been produced (only when flush is set to
-  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
-  if next_in or next_out was NULL), Z_BUF_ERROR if no progress is possible
-  (for example avail_in or avail_out was zero). Note that Z_BUF_ERROR is not
-  fatal, and deflate() can be called again with more input and more output

-ZEXTERN int ZEXPORT inflate OF((z_streamp strm, int flush));
-/*
-    inflate decompresses as much data as possible, and stops when the input
-  buffer becomes empty or the output buffer becomes full. It may introduce
-  some output latency (reading input without producing any output) except when
-  forced to flush.
-
-  The detailed semantics are as follows. inflate performs one or both of the
-  following actions:
-
-  - Decompress more input starting at next_in and update next_in and avail_in
-    accordingly. If not all input can be processed (because there is not
-    enough room in the output buffer), next_in is updated and processing
-    will resume at this point for the next call of inflate().
-
-  - Provide more output starting at next_out and update next_out and avail_out
-    accordingly.  inflate() provides as much output as possible, until there
-    is no more input data or no more space in the output buffer (see below
-    about the flush parameter).
-
-  Before the call of inflate(), the application should ensure that at least
-  one of the actions is possible, by providing more input and/or consuming
-  more output, and updating the next_* and avail_* values accordingly.
-  The application can consume the uncompressed output when it wants, for
-  example when the output buffer is full (avail_out == 0), or after each
-  call of inflate(). If inflate returns Z_OK and with zero avail_out, it
-  must be called again after making room in the output buffer because there
-  might be more output pending.
-
-    The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH,
-  Z_FINISH, or Z_BLOCK. Z_SYNC_FLUSH requests that inflate() flush as much
-  output as possible to the output buffer. Z_BLOCK requests that inflate() stop
-  if and when it gets to the next deflate block boundary. When decoding the
-  zlib or gzip format, this will cause inflate() to return immediately after
-  the header and before the first block. When doing a raw inflate, inflate()
-  will go ahead and process the first block, and will return when it gets to
-  the end of that block, or when it runs out of data.
-
-    The Z_BLOCK option assists in appending to or combining deflate streams.
-  Also to assist in this, on return inflate() will set strm->data_type to the
-  number of unused bits in the last byte taken from strm->next_in, plus 64
-  if inflate() is currently decoding the last block in the deflate stream,
-  plus 128 if inflate() returned immediately after decoding an end-of-block
-  code or decoding the complete header up to just before the first byte of the
-  deflate stream. The end-of-block will not be indicated until all of the
-  uncompressed data from that block has been written to strm->next_out.  The
-  number of unused bits may in general be greater than seven, except when
-  bit 7 of data_type is set, in which case the number of unused bits will be
-  less than eight.
-
-    inflate() should normally be called until it returns Z_STREAM_END or an
-  error. However if all decompression is to be performed in a single step
-  (a single call of inflate), the parameter flush should be set to
-  Z_FINISH. In this case all pending input is processed and all pending
-  output is flushed; avail_out must be large enough to hold all the
-  uncompressed data. (The size of the uncompressed data may have been saved
-  by the compressor for this purpose.) The next operation on this stream must
-  be inflateEnd to deallocate the decompression state. The use of Z_FINISH
-  is never required, but can be used to inform inflate that a faster approach
-  may be used for the single inflate() call.
-
-     In this implementation, inflate() always flushes as much output as
-  possible to the output buffer, and always uses the faster approach on the
-  first call. So the only effect of the flush parameter in this implementation
-  is on the return value of inflate(), as noted below, or when it returns early
-  because Z_BLOCK is used.
-
-     If a preset dictionary is needed after this call (see inflateSetDictionary
-  below), inflate sets strm->adler to the adler32 checksum of the dictionary
-  chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
-  strm->adler to the adler32 checksum of all output produced so far (that is,
-  total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
-  below. At the end of the stream, inflate() checks that its computed adler32
-  checksum is equal to that saved by the compressor and returns Z_STREAM_END
-  only if the checksum is correct.
-
-    inflate() will decompress and check either zlib-wrapped or gzip-wrapped
-  deflate data.  The header type is detected automatically.  Any information
-  contained in the gzip header is not retained, so applications that need that
-  information should instead use raw inflate, see inflateInit2() below, or
-  inflateBack() and perform their own processing of the gzip header and
-  trailer.
-
-    inflate() returns Z_OK if some progress has been made (more input processed
-  or more output produced), Z_STREAM_END if the end of the compressed data has
-  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
-  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
-  corrupted (input stream not conforming to the zlib format or incorrect check
-  value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
-  if next_in or next_out was NULL), Z_MEM_ERROR if there was not enough memory,
-  Z_BUF_ERROR if no progress is possible or if there was not enough room in the
-  output buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and
-  inflate() can be called again with more input and more output space to
-  continue decompressing. If Z_DATA_ERROR is returned, the application may then
-  call inflateSync() to look for a good compression block if a partial recovery

-
-     This is another version of deflateInit with more compression options. The
-   fields next_in, zalloc, zfree and opaque must be initialized before by
-   the caller.
-
-     The method parameter is the compression method. It must be Z_DEFLATED in
-   this version of the library.
-
-     The windowBits parameter is the base two logarithm of the window size
-   (the size of the history buffer). It should be in the range 8..15 for this
-   version of the library. Larger values of this parameter result in better
-   compression at the expense of memory usage. The default value is 15 if
-   deflateInit is used instead.
-
-     windowBits can also be -8..-15 for raw deflate. In this case, -windowBits
-   determines the window size. deflate() will then generate raw deflate data
-   with no zlib header or trailer, and will not compute an adler32 check value.
-
-     windowBits can also be greater than 15 for optional gzip encoding. Add
-   16 to windowBits to write a simple gzip header and trailer around the
-   compressed data instead of a zlib wrapper. The gzip header will have no
-   file name, no extra data, no comment, no modification time (set to zero),
-   no header crc, and the operating system will be set to 255 (unknown).  If a
-   gzip stream is being written, strm->adler is a crc32 instead of an adler32.
-
-     The memLevel parameter specifies how much memory should be allocated
-   for the internal compression state. memLevel=1 uses minimum memory but
-   is slow and reduces compression ratio; memLevel=9 uses maximum memory
-   for optimal speed. The default value is 8. See zconf.h for total memory
-   usage as a function of windowBits and memLevel.
-
-     The strategy parameter is used to tune the compression algorithm. Use the
-   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
-   filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
-   string match), or Z_RLE to limit match distances to one (run-length
-   encoding). Filtered data consists mostly of small values with a somewhat
-   random distribution. In this case, the compression algorithm is tuned to
-   compress them better. The effect of Z_FILTERED is to force more Huffman
-   coding and less string matching; it is somewhat intermediate between
-   Z_DEFAULT and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as fast as
-   Z_HUFFMAN_ONLY, but give better compression for PNG image data. The strategy
-   parameter only affects the compression ratio but not the correctness of the
-   compressed output even if it is not set appropriately.  Z_FIXED prevents the
-   use of dynamic Huffman codes, allowing for a simpler decoder for special
-   applications.
-
-      deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
-   memory, Z_STREAM_ERROR if a parameter is invalid (such as an invalid
-   method). msg is set to null if there is no error message.  deflateInit2 does
-   not perform any compression: this will be done by deflate().

-   dictionary (see inflateSetDictionary).
-
-     The dictionary should consist of strings (byte sequences) that are likely
-   to be encountered later in the data to be compressed, with the most commonly
-   used strings preferably put towards the end of the dictionary. Using a

-
-      The text, time, xflags, and os fields are filled in with the gzip header

-/*
-     inflateBack() does a raw inflate with a single call using a call-back
-   interface for input and output.  This is more efficient than inflate() for
-   file i/o applications in that it avoids copying between the output and the
-   sliding window by simply making the window itself the output buffer.  This
-   function trusts the application to not change the output buffer passed by
-   the output function, at least until inflateBack() returns.
-
-     inflateBackInit() must be called first to allocate the internal state
-   and to initialize the state with the user-provided window buffer.
-   inflateBack() may then be used multiple times to inflate a complete, raw
-   deflate stream with each call.  inflateBackEnd() is then called to free
-   the allocated state.
-
-     A raw deflate stream is one with no zlib or gzip header or trailer.
-   This routine would normally be used in a utility that reads zip or gzip
-   files and writes out uncompressed files.  The utility would decode the
-   header and process the trailer on its own, hence this routine expects
-   only the raw deflate stream to decompress.  This is different from the
-   normal behavior of inflate(), which expects either a zlib or gzip header and
-   trailer around the deflate stream.
-
-     inflateBack() uses two subroutines supplied by the caller that are then
-   called by inflateBack() for input and output.  inflateBack() calls those
-   routines until it reads a complete deflate stream and writes out all of the
-   uncompressed data, or until it encounters an error.  The function's
-   parameters and return types are defined above in the in_func and out_func
-   typedefs.  inflateBack() will call in(in_desc, &buf) which should return the
-   number of bytes of provided input, and a pointer to that input in buf.  If
-   there is no input available, in() must return zero--buf is ignored in that
-   case--and inflateBack() will return a buffer error.  inflateBack() will call
-   out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].  out()
-   should return zero on success, or non-zero on failure.  If out() returns
-   non-zero, inflateBack() will return with an error.  Neither in() nor out()
-   are permitted to change the contents of the window provided to
-   inflateBackInit(), which is also the buffer that out() uses to write from.
-   The length written by out() will be at most the window size.  Any non-zero
-   amount of input may be provided by in().
-
-     For convenience, inflateBack() can be provided input on the first call by
-   setting strm->next_in and strm->avail_in.  If that input is exhausted, then
-   in() will be called.  Therefore strm->next_in must be initialized before
-   calling inflateBack().  If strm->next_in is Z_NULL, then in() will be called
-   immediately for input.  If strm->next_in is not Z_NULL, then strm->avail_in
-   must also be initialized, and then if strm->avail_in is not zero, input will
-   initially be taken from strm->next_in[0 .. strm->avail_in - 1].
-
-     The in_desc and out_desc parameters of inflateBack() is passed as the
-   first parameter of in() and out() respectively when they are called.  These
-   descriptors can be optionally used to pass any information that the caller-
-   supplied in() and out() functions need to do their job.
-
-     On return, inflateBack() will set strm->next_in and strm->avail_in to
-   pass back any unused input that was provided by the last in() call.  The
-   return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
-   if in() or out() returned an error, Z_DATA_ERROR if there was a format
-   error in the deflate stream (in which case strm->msg is set to indicate the
-   nature of the error), or Z_STREAM_ERROR if the stream was not properly
-   initialized.  In the case of Z_BUF_ERROR, an input or output error can be
-   distinguished using strm->next_in which will be Z_NULL only if in() returned
-   an error.  If strm->next is not Z_NULL, then the Z_BUF_ERROR was due to
-   out() returning non-zero.  (in() will always be called before out(), so
-   strm->next_in is assured to be defined if out() returns non-zero.)  Note
-   that inflateBack() cannot return Z_OK.
