-# a client sdk for StatsD, written in C++
-
-## API
-See [header file](src/statsd_client.h) for more api detail.
-
-** Notice: this client is not thread-safe **
-
-## Demo
-### test\_client
-This simple demo shows how the use this client.
-
-### system\_monitor
-This is a daemon for monitoring a Linux system.
-It'll wake up every minute and monitor the following:
-
-* load
-* cpu
-* free memory
-* free swap (disabled)
-* received bytes
-* transmitted bytes
-* procs
-* uptime
-
-The stats sent to statsd will be in "host.MACAddress" namespace.
-
-Usage:
-
-    system_monitor statsd-host interface-to-monitor
-
-e.g.
-
-    `system_monitor 172.16.42.1 eth0`

-
-                Frequently Asked Questions about zlib
-
-
-If your question is not there, please check the zlib home page
-http://zlib.net/ which may have more recent information.
-The lastest zlib FAQ is at http://zlib.net/zlib_faq.html
-
-
- 1. Is zlib Y2K-compliant?
-
-    Yes. zlib doesn't handle dates.
-
- 2. Where can I get a Windows DLL version?
-
-    The zlib sources can be compiled without change to produce a DLL.  See the
-    file win32/DLL_FAQ.txt in the zlib distribution.  Pointers to the
-    precompiled DLL are found in the zlib web site at http://zlib.net/ .
-
- 3. Where can I get a Visual Basic interface to zlib?
-
-    See
-        * http://marknelson.us/1997/01/01/zlib-engine/
-        * win32/DLL_FAQ.txt in the zlib distribution
-
- 4. compress() returns Z_BUF_ERROR.
-
-    Make sure that before the call of compress(), the length of the compressed
-    buffer is equal to the available size of the compressed buffer and not
-    zero.  For Visual Basic, check that this parameter is passed by reference
-    ("as any"), not by value ("as long").
-
- 5. deflate() or inflate() returns Z_BUF_ERROR.
-
-    Before making the call, make sure that avail_in and avail_out are not zero.
-    When setting the parameter flush equal to Z_FINISH, also make sure that
-    avail_out is big enough to allow processing all pending input.  Note that a
-    Z_BUF_ERROR is not fatal--another call to deflate() or inflate() can be
-    made with more input or output space.  A Z_BUF_ERROR may in fact be
-    unavoidable depending on how the functions are used, since it is not
-    possible to tell whether or not there is more output pending when
-    strm.avail_out returns with zero.  See http://zlib.net/zlib_how.html for a
-    heavily annotated example.
-
- 6. Where's the zlib documentation (man pages, etc.)?
-
-    It's in zlib.h .  Examples of zlib usage are in the files test/example.c
-    and test/minigzip.c, with more in examples/ .
-
- 7. Why don't you use GNU autoconf or libtool or ...?
-
-    Because we would like to keep zlib as a very small and simple package.
-    zlib is rather portable and doesn't need much configuration.
-
- 8. I found a bug in zlib.
-
-    Most of the time, such problems are due to an incorrect usage of zlib.
-    Please try to reproduce the problem with a small program and send the
-    corresponding source to us at zlib@gzip.org .  Do not send multi-megabyte
-    data files without prior agreement.
-
- 9. Why do I get "undefined reference to gzputc"?
-
-    If "make test" produces something like
-
-       example.o(.text+0x154): undefined reference to `gzputc'
-
-    check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
-    /usr/X11R6/lib. Remove any old versions, then do "make install".
-
-10. I need a Delphi interface to zlib.
-
-    See the contrib/delphi directory in the zlib distribution.
-
-11. Can zlib handle .zip archives?
-
-    Not by itself, no.  See the directory contrib/minizip in the zlib
-    distribution.
-
-12. Can zlib handle .Z files?
-
-    No, sorry.  You have to spawn an uncompress or gunzip subprocess, or adapt
-    the code of uncompress on your own.
-
-13. How can I make a Unix shared library?
-
-    By default a shared (and a static) library is built for Unix.  So:
-
-    make distclean
-    ./configure
-    make
-
-14. How do I install a shared zlib library on Unix?
-
-    After the above, then:
-
-    make install
-
-    However, many flavors of Unix come with a shared zlib already installed.
-    Before going to the trouble of compiling a shared version of zlib and
-    trying to install it, you may want to check if it's already there!  If you
-    can #include <zlib.h>, it's there.  The -lz option will probably link to
-    it.  You can check the version at the top of zlib.h or with the
-    ZLIB_VERSION symbol defined in zlib.h .
-
-15. I have a question about OttoPDF.
-
-    We are not the authors of OttoPDF. The real author is on the OttoPDF web
-    site: Joel Hainley, jhainley@myndkryme.com.
-
-16. Can zlib decode Flate data in an Adobe PDF file?
-
-    Yes. See http://www.pdflib.com/ . To modify PDF forms, see
-    http://sourceforge.net/projects/acroformtool/ .
-
-17. Why am I getting this "register_frame_info not found" error on Solaris?
-
-    After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib
-    generates an error such as:
-
-        ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so:
-        symbol __register_frame_info: referenced symbol not found
-
-    The symbol __register_frame_info is not part of zlib, it is generated by
-    the C compiler (cc or gcc).  You must recompile applications using zlib
-    which have this problem.  This problem is specific to Solaris.  See
-    http://www.sunfreeware.com for Solaris versions of zlib and applications
-    using zlib.
-
-18. Why does gzip give an error on a file I make with compress/deflate?
-
-    The compress and deflate functions produce data in the zlib format, which
-    is different and incompatible with the gzip format.  The gz* functions in
-    zlib on the other hand use the gzip format.  Both the zlib and gzip formats
-    use the same compressed data format internally, but have different headers
-    and trailers around the compressed data.
-
-19. Ok, so why are there two different formats?
-
-    The gzip format was designed to retain the directory information about a
-    single file, such as the name and last modification date.  The zlib format
-    on the other hand was designed for in-memory and communication channel
-    applications, and has a much more compact header and trailer and uses a
-    faster integrity check than gzip.
-
-20. Well that's nice, but how do I make a gzip file in memory?
-
-    You can request that deflate write the gzip format instead of the zlib
-    format using deflateInit2().  You can also request that inflate decode the
-    gzip format using inflateInit2().  Read zlib.h for more details.
-
-21. Is zlib thread-safe?
-
-    Yes.  However any library routines that zlib uses and any application-
-    provided memory allocation routines must also be thread-safe.  zlib's gz*
-    functions use stdio library routines, and most of zlib's functions use the
-    library memory allocation routines by default.  zlib's *Init* functions
-    allow for the application to provide custom memory allocation routines.
-
-    Of course, you should only operate on any given zlib or gzip stream from a
-    single thread at a time.
-
-22. Can I use zlib in my commercial application?
-
-    Yes.  Please read the license in zlib.h.
-
-23. Is zlib under the GNU license?
-
-    No.  Please read the license in zlib.h.
-
-24. The license says that altered source versions must be "plainly marked". So
-    what exactly do I need to do to meet that requirement?
-
-    You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h.  In
-    particular, the final version number needs to be changed to "f", and an
-    identification string should be appended to ZLIB_VERSION.  Version numbers
-    x.x.x.f are reserved for modifications to zlib by others than the zlib
-    maintainers.  For example, if the version of the base zlib you are altering
-    is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
-    ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3".  You can also
-    update the version strings in deflate.c and inftrees.c.
-
-    For altered source distributions, you should also note the origin and
-    nature of the changes in zlib.h, as well as in ChangeLog and README, along
-    with the dates of the alterations.  The origin should include at least your
-    name (or your company's name), and an email address to contact for help or
-    issues with the library.
-
-    Note that distributing a compiled zlib library along with zlib.h and
-    zconf.h is also a source distribution, and so you should change
-    ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes
-    in zlib.h as you would for a full source distribution.
-
-25. Will zlib work on a big-endian or little-endian architecture, and can I
-    exchange compressed data between them?
-
-    Yes and yes.
-
-26. Will zlib work on a 64-bit machine?
-
-    Yes.  It has been tested on 64-bit machines, and has no dependence on any
-    data types being limited to 32-bits in length.  If you have any
-    difficulties, please provide a complete problem report to zlib@gzip.org
-
-27. Will zlib decompress data from the PKWare Data Compression Library?
-
-    No.  The PKWare DCL uses a completely different compressed data format than
-    does PKZIP and zlib.  However, you can look in zlib's contrib/blast
-    directory for a possible solution to your problem.
-
-28. Can I access data randomly in a compressed stream?
-
-    No, not without some preparation.  If when compressing you periodically use
-    Z_FULL_FLUSH, carefully write all the pending data at those points, and
-    keep an index of those locations, then you can start decompression at those
-    points.  You have to be careful to not use Z_FULL_FLUSH too often, since it
-    can significantly degrade compression.  Alternatively, you can scan a
-    deflate stream once to generate an index, and then use that index for
-    random access.  See examples/zran.c .
-
-29. Does zlib work on MVS, OS/390, CICS, etc.?
-
-    It has in the past, but we have not heard of any recent evidence.  There
-    were working ports of zlib 1.1.4 to MVS, but those links no longer work.
-    If you know of recent, successful applications of zlib on these operating
-    systems, please let us know.  Thanks.
-
-30. Is there some simpler, easier to read version of inflate I can look at to
-    understand the deflate format?
-
-    First off, you should read RFC 1951.  Second, yes.  Look in zlib's
-    contrib/puff directory.
-
-31. Does zlib infringe on any patents?
-
-    As far as we know, no.  In fact, that was originally the whole point behind
-    zlib.  Look here for some more information:
-
-    http://www.gzip.org/#faq11
-
-32. Can zlib work with greater than 4 GB of data?
-
-    Yes.  inflate() and deflate() will process any amount of data correctly.
-    Each call of inflate() or deflate() is limited to input and output chunks
-    of the maximum value that can be stored in the compiler's "unsigned int"
-    type, but there is no limit to the number of chunks.  Note however that the
-    strm.total_in and strm_total_out counters may be limited to 4 GB.  These
-    counters are provided as a convenience and are not used internally by
-    inflate() or deflate().  The application can easily set up its own counters
-    updated after each call of inflate() or deflate() to count beyond 4 GB.
-    compress() and uncompress() may be limited to 4 GB, since they operate in a
-    single call.  gzseek() and gztell() may be limited to 4 GB depending on how
-    zlib is compiled.  See the zlibCompileFlags() function in zlib.h.
-
-    The word "may" appears several times above since there is a 4 GB limit only
-    if the compiler's "long" type is 32 bits.  If the compiler's "long" type is
-    64 bits, then the limit is 16 exabytes.
-
-33. Does zlib have any security vulnerabilities?
-
-    The only one that we are aware of is potentially in gzprintf().  If zlib is
-    compiled to use sprintf() or vsprintf(), then there is no protection
-    against a buffer overflow of an 8K string space (or other value as set by
-    gzbuffer()), other than the caller of gzprintf() assuring that the output
-    will not exceed 8K.  On the other hand, if zlib is compiled to use
-    snprintf() or vsnprintf(), which should normally be the case, then there is
-    no vulnerability.  The ./configure script will display warnings if an
-    insecure variation of sprintf() will be used by gzprintf().  Also the
-    zlibCompileFlags() function will return information on what variant of
-    sprintf() is used by gzprintf().
-
-    If you don't have snprintf() or vsnprintf() and would like one, you can
-    find a portable implementation here:
-
-        http://www.ijs.si/software/snprintf/
-
-    Note that you should be using the most recent version of zlib.  Versions
-    1.1.3 and before were subject to a double-free vulnerability, and versions
-    1.2.1 and 1.2.2 were subject to an access exception when decompressing
-    invalid compressed data.
-
-34. Is there a Java version of zlib?
-
-    Probably what you want is to use zlib in Java. zlib is already included
-    as part of the Java SDK in the java.util.zip package. If you really want
-    a version of zlib written in the Java language, look on the zlib home
-    page for links: http://zlib.net/ .
-
-35. I get this or that compiler or source-code scanner warning when I crank it
-    up to maximally-pedantic. Can't you guys write proper code?
-
-    Many years ago, we gave up attempting to avoid warnings on every compiler
-    in the universe.  It just got to be a waste of time, and some compilers
-    were downright silly as well as contradicted each other.  So now, we simply
-    make sure that the code always works.
-
-36. Valgrind (or some similar memory access checker) says that deflate is
-    performing a conditional jump that depends on an uninitialized value.
-    Isn't that a bug?
-
-    No.  That is intentional for performance reasons, and the output of deflate
-    is not affected.  This only started showing up recently since zlib 1.2.x
-    uses malloc() by default for allocations, whereas earlier versions used
-    calloc(), which zeros out the allocated memory.  Even though the code was
-    correct, versions 1.2.4 and later was changed to not stimulate these
-    checkers.
-
-37. Will zlib read the (insert any ancient or arcane format here) compressed
-    data format?
-
-    Probably not. Look in the comp.compression FAQ for pointers to various
-    formats and associated software.
-
-38. How can I encrypt/decrypt zip files with zlib?
-
-    zlib doesn't support encryption.  The original PKZIP encryption is very
-    weak and can be broken with freely available programs.  To get strong
-    encryption, use GnuPG, http://www.gnupg.org/ , which already includes zlib
-    compression.  For PKZIP compatible "encryption", look at
-    http://www.info-zip.org/
-
-39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings?
-
-    "gzip" is the gzip format, and "deflate" is the zlib format.  They should
-    probably have called the second one "zlib" instead to avoid confusion with
-    the raw deflate compressed data format.  While the HTTP 1.1 RFC 2616
-    correctly points to the zlib specification in RFC 1950 for the "deflate"
-    transfer encoding, there have been reports of servers and browsers that
-    incorrectly produce or expect raw deflate data per the deflate
-    specification in RFC 1951, most notably Microsoft.  So even though the
-    "deflate" transfer encoding using the zlib format would be the more
-    efficient approach (and in fact exactly what the zlib format was designed
-    for), using the "gzip" transfer encoding is probably more reliable due to
-    an unfortunate choice of name on the part of the HTTP 1.1 authors.
-
-    Bottom line: use the gzip format for HTTP 1.1 encoding.
-
-40. Does zlib support the new "Deflate64" format introduced by PKWare?
-
-    No.  PKWare has apparently decided to keep that format proprietary, since
-    they have not documented it as they have previous compression formats.  In
-    any case, the compression improvements are so modest compared to other more
-    modern approaches, that it's not worth the effort to implement.
-
-41. I'm having a problem with the zip functions in zlib, can you help?
-
-    There are no zip functions in zlib.  You are probably using minizip by
-    Giles Vollant, which is found in the contrib directory of zlib.  It is not
-    part of zlib.  In fact none of the stuff in contrib is part of zlib.  The
-    files in there are not supported by the zlib authors.  You need to contact
-    the authors of the respective contribution for help.
-
-42. The match.asm code in contrib is under the GNU General Public License.
-    Since it's part of zlib, doesn't that mean that all of zlib falls under the
-    GNU GPL?
-
-    No.  The files in contrib are not part of zlib.  They were contributed by
-    other authors and are provided as a convenience to the user within the zlib
-    distribution.  Each item in contrib has its own license.
-
-43. Is zlib subject to export controls?  What is its ECCN?
-
-    zlib is not subject to export controls, and so is classified as EAR99.
-
-44. Can you please sign these lengthy legal documents and fax them back to us
-    so that we can use your software in our product?
-
-    No. Go away. Shoo.
