+Short story (If you already have ruby and cmake):
+
+./configure && make install
+
+When things go wrong:
+
+attain CMake (http://www.cmake.org) and ruby (http://ruby-lang.org) and
+try again.
+
+OR, attain CMake and build by hand:
+
+1. mkdir build
+2. cd build
+3. cmake ..
+4. make
+5. build output left in yajl-X.Y.Z
+
+NOTE: for 64-bit systems where lib64 is used you can pass the cmake
+ variable LIB_SUFFIX to cause installation into the system's 'lib64'
+ directory.
+
+best,

+YAJL has been successfully built using Visual Studio 8. CMake, a
+build file generator, is used to build the software. CMake supports
+several different build environments, so you may either build YAJL
+using the IDE via the following steps:
+
+1. acquire cmake (http://www.cmake.org)
+2. mkdir build
+3. cd build
+4. cmake ..
+5. devenv YetAnotherJSONParser.sln /project ALL_BUILD /build Release
+6. build output is left in build/yajl-X.Y.Z
+
+Or you can build from the command line using nmake:
+
+1. Click Start > Programs > Microsoft Visual Studio > Visual Studio
+Tools > Visual Studio Command Prompt -- for your version of Visual
+Studio, which will open a command prompt. You may verify that the
+compiler is in your path by typing "cl /?" at the prompt.
+2. cd C:\path\to\yajl\source\
+3. mkdir build
+4. cd build
+5. cmake -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=Release ..
+6. nmake
+7. nmake install
+
+Earlier versions of visual studio and other build generators haven't
+been thoroughly tested, but should work without any major issues.

+ * @lloyd - json_reformat supports -s flag for stream processing
+
+2.0.4
+ * @jcekstrom - additional checking in integer parsing
+ * @jcekstrom - fix a bug in yajl_tree that would cause valid json integersto fail to parse
+ * @plaguemorin - fix a memory leak in yajl_tree (error strings were being leaked)
+ * @7AC - reset errno
+ * @ConradIrwin - include flags to reformatter to allow toggling of escape solidus option
+
+2.0.3
+ * John Stamp generation of a pkgconfig file at build time.
+ * @robzuber bugfix in yajl_tree_get()
+ * @lloyd - fix for compilation on 64 bit windows
+
+2.0.2

+ * lth 20-35% (osx and linux respectively) parsing performance
+ improvement attained by tweaking string scanning (idea: @michaelrhanson).
+ * Florian Forster & lth - yajl_tree interface introduced as a higher level
+ interface to the parser (eats JSON, poops a memory representation)
+ * lth require a C99 compiler
+ * lth integers are now represented with long long (64bit+) on all platforms.

+**********************************************************************
+
+Welcome to Yet Another JSON Library (YAJL)
+
+## Why does the world need another C library for parsing JSON?
+
+Good question. In a review of current C JSON parsing libraries I was
+unable to find one that satisfies my requirements. Those are,
+0. written in C
+1. portable
+2. robust -- as close to "crash proof" as possible
+3. data representation independent
+4. fast
+5. generates verbose, useful error messages including context of where
+ the error occurs in the input text.
+6. can parse JSON data off a stream, incrementally
+7. simple to use
+8. tiny
+
+Numbers 3, 5, 6, and 7 were particularly hard to find, and were what
+caused me to ultimately create YAJL. This document is a tour of some
+of the more important aspects of YAJL.
+
+## YAJL is Free.
+
+Permissive licensing means you can use it in open source and
+commercial products alike without any fees. My request beyond the
+licensing is that if you find bugs drop me a email, or better yet,
+fork and fix.
+
+Porting YAJL should be trivial, the implementation is ANSI C. If you
+port to new systems I'd love to hear of it and integrate your patches.
+
+## YAJL is data representation independent.
+
+BYODR! Many JSON libraries impose a structure based data representation
+on you. This is a benefit in some cases and a drawback in others.
+YAJL uses callbacks to remain agnostic of the in-memory representation.
+So if you wish to build up an in-memory representation, you may do so
+using YAJL, but you must bring the code that defines and populates the
+in memory structure.
+
+This also means that YAJL can be used by other (higher level) JSON
+libraries if so desired.
+
+## YAJL supports stream parsing
+
+This means you do not need to hold the whole JSON representation in
+textual form in memory. This makes YAJL ideal for filtering projects,
+where you're converting YAJL from one form to another (i.e. XML). The
+included JSON pretty printer is an example of such a filter program.
+
+## YAJL is fast
+
+Minimal memory copying is performed. YAJL, when possible, returns
+pointers into the client provided text (i.e. for strings that have no
+embedded escape chars, hopefully the common case). I've put a lot of
+effort into profiling and tuning performance, but I have ignored a
+couple possible performance improvements to keep the interface clean,
+small, and flexible. My hope is that YAJL will perform comparably to
+the fastest JSON parser out there.
+
+YAJL should impose both minimal CPU and memory requirements on your
+application.
+
+## YAJL is tiny.
+
+Fat free. No whip.
+
+enjoy,
+Lloyd - July, 2007

+/* Impact of the stream parsing feature on the lexer:
+ *
+ * YAJL support stream parsing. That is, the ability to parse the first
+ * bits of a chunk of JSON before the last bits are available (still on
+ * the network or disk). This makes the lexer more complex. The
+ * responsibility of the lexer is to handle transparently the case where
+ * a chunk boundary falls in the middle of a token. This is
+ * accomplished is via a buffer and a character reading abstraction.
+ *
+ * Overview of implementation
+ *
+ * When we lex to end of input string before end of token is hit, we
+ * copy all of the input text composing the token into our lexBuf.
+ *
+ * Every time we read a character, we do so through the readChar function.
+ * readChar's responsibility is to handle pulling all chars from the buffer
+ * before pulling chars from input text
