Switched project label to use 'nicer' suffix (e.g., md instead of /MD)

It seems that it's not necessary to export those members (as long as you can't access them), and most of them are STL instances, which apparently cause lots of problems for DLLs. (For example, you simply can't export instances of std::map; see http://support.microsoft.com/kb/168958.)

-# The following is a list of breaking changes to yaml-cpp, by version #
-
-# New API #
-
-## 0.5.2 ##
-
-_none_
-
-## 0.5.1 ##
-
-  * `Node::clear` was replaced by `Node::reset`, which takes an optional node, similar to smart pointers.
-
-## 0.5.0 ##
-
-Initial version of the new API.
-
-# Old API #
-
-## 0.3.0 ##
-
-_none_
-
-## 0.2.7 ##
-
-  * `YAML::Binary` now takes `const unsigned char *` for the binary data (instead of `const char *`).
-
-## 0.2.6 ##
-
-  * `Node::GetType()` is now `Node::Type()`, and returns an enum `NodeType::value`, where:
-> > ` struct NodeType { enum value { Null, Scalar, Sequence, Map }; }; `
-  * `Node::GetTag()` is now `Node::Tag()`
-  * `Node::Identity()` is removed, and `Node::IsAlias()` and `Node::IsReferenced()` have been merged into `Node::IsAliased()`. The reason: there's no reason to distinguish an alias node from its anchor - whichever happens to be emitted first will be the anchor, and the rest will be aliases.
-  * `Node::Read<T>` is now `Node::to<T>`. This wasn't a documented function, so it shouldn't break anything.
-  * `Node`'s comparison operators (for example, `operator == (const Node&, const T&)`) have all been removed. These weren't documented either (they were just used for the tests), so this shouldn't break anything either.
-  * The emitter no longer produces the document start by default - if you want it, you can supply it with the manipulator `YAML::BeginDoc`.
-
-## 0.2.5 ##

-This wiki was started with v0.2.5.

-### Note: this page is no longer relevant since yaml-cpp now includes an emitter. I'm leaving it here for future reference, though, but it will no longer be updated. ###
-
-# Introduction #
-
-Currently, yaml-cpp is just a YAML parser with an emitter that simply parrots back a pre-parsed YAML document. It would be nice to be able to generate YAML documents (and then write them), but I'm not convinced what an ideal API would look like for this.
-
-The purpose of this document is to compile a list of possible ways to generate YAML documents. Please leave comments critiquing the solutions, or providing your own. The idea (at the moment) is **not** to write the actual behind-the-scenes code, but rather to describe an API, and so to write samples of what a user of this API would write.
-
-I'll be updating this wiki based on the comments that people leave. Also, if you like, indicate whether or not such an API would be useful to you.
-
-# Copy/Assignment Method #
-
-This method uses the copy constructors, assignment operators, and STL-like member functions for generating the content, and then the (existing) operator << to write it.
-
-```
-// basic scalars
-YAML::Node scalar = "Hello World";
-YAML::Node number = 52;
-
-// sequence
-YAML::Node sequence;
-sequence.push_back(scalar);
-sequence.push_back(number);
-
-// map
-YAML::Node price;
-price["monitor"] = 250;
-price["RAM (1GB)"] = 70;
-price["some random sequence"] = sequence;
-```
-
-Potential problems:
-  * How to generate anchors/aliases
-  * How to generate directives
-  * How to indicate inline sequences and maps

-# Stream method #
-
-This is a combination of the above Writer method and STL ostream manipulators.
-
-The simple case:
-```
-YAML::Emitter out;
-out << "Hello, World!";
-out.WriteToFile("out.yaml");
-// Hello, World!
-std::ofstream fout("other.yaml");
-out.WriteToStream(fout);
-// same thing
-```
-A simple list:
-```
-YAML::Emitter out;
-out << YAML::BeginSeq;
-out << "eggs";
-out << "bread";
-out << "milk";
-out << YAML::EndSeq;  // if we omit this, should we a) throw or b) assume it's there?
-// - eggs
-// - bread
-// - milk
-```
-A simple map:
-```
-YAML::Emitter out;
-out << YAML::BeginMap;
-out << YAML::Key << "name";  // should we instead have a one-off method for creating a key/value pair?
-out << YAML::Value << "Ryan Braun";
-out << YAML::Key << "position";
-out << YAML::Value << "3B";
-out << YAML::EndMap;
-// name: Ryan Braun
-// position: 3B
-```
-Examples can be mixed:
-```
-YAML::Emitter out;
-out << YAML::BeginMap;
-out << YAML::Key << "name";
-out << YAML::Value << "Barack Obama";
-out << YAML::Key << "children";
-out << YAML::Value << YAML::BeginSeq << "Sasha" << "Malia" << YAML::EndSeq;
-out << YAML::EndMap;
-// name: Barack Obama
-// children:
-//   - Sasha
-//   - Malia
-```
-Output format can be modified using manipulators:
-```
-YAML::Emitter out;
-out << YAML::Literal << "A\n B\n  C";
-// |
-// A
-//  B
-//   C
-```
-```
-YAML::Emitter out;
-out << YAML::Flow;
-out << YAML::BeginSeq << 2 << 3 << 5 << 7 << 11 < YAML::EndSeq;
-// [2, 3, 5, 7, 11]
-```
-We can also have comments:
-```
-YAML::Emitter out;
-out << YAML::BeginMap;
-out << YAML::Key << "method";
-out << YAML::Value << "least squares";
-out << YAML::Comment("should we change this method?");
-out << YAML::EndMap;
-// method: least squares # should we change this method?
-```
-And aliases/anchors:
-```
-YAML::Emitter out;
-out << YAML::BeginSeq;
-out << YAML::Anchor("fred");
-out << YAML::BeginMap;
-out << YAML::Key << "name" << YAML::Value << "Fred";
-out << YAML::Key << "age" << YAML::Value << "42";
-out << YAML::EndMap;
-out << YAML::Alias("fred");
-out << YAML::EndSeq;
-// - &fred
-//   name: Fred
-//   age: 42
-// - *fred
-```
-As usual, we can overload `operator <<`:
-```
-struct Vec3 { int x; int y; int z; };
-YAML::Emitter& operator << (YAML::Emitter& out, const Vec3& v) {
-	out << YAML::Flow;
-	out << YAML::BeginSeq << v.x << v.y << v.z << YAML:EndSeq;
-	return out;
-}
-```
-We'll provide overloads for STL vectors (and lists and sets and any container with an iterator and a dereferencable value?)
-```
-YAML::Emitter out;
-std::vector <int> values;
-values.push_back(3);
-values.push_back(5);
-out << values;
-// - 3
-// - 5
-```
-... and maps:
-```
-YAML::Emitter out;
-std::map <std::string, int> ages;
-ages["Daniel"] = 26;
-ages["Jesse"] = 24;
-out << ages;
-// Daniel: 26
-// Jesse: 24
-```
-All manipulators affect **only** the next item in the stream they all have global setters that can be **locally** changed using a manipulator:
-```
-YAML::Emitter out;
-out.SetIndent(4);
-out.SetMapStyle(YAML::Flow);
-```
-
-List of string manipulators:
-```
-YAML::Auto;  // auto-detect - try for no quotes, but put double quotes if necessary
-YAML::SingleQuoted;
-YAML::DoubleQuoted;
-YAML::Literal;
-```
-List of bool manipulators:
-```
-YAML::YesNoBool;  // yes, no
-YAML::TrueFalseBool;  // true, false
-YAML::OnOffBool;  // on, off
-YAML::UpperCase;  // TRUE, N
-YAML::LowerCase;  // f, yes
-YAML::CamelCase;  // No, Off
-YAML::LongBool;  // yes, On
-YAML::ShortBool;  // y, t
-```
-List of int manipulators:
-```
-YAML::Dec;
-YAML::Hex;
-YAML::Oct;
-```
-List of sequence manipulators:
-```
-YAML::Flow;
-YAML::Block;
-```
-List of map manipulators:
-```
-YAML::Flow;
-YAML::Block;
-YAML::Auto;  // auto-detect key - try for simple key, but make it a long key if necessary
-YAML::LongKey;
-```
-Note about sequence/map manipulators: they're the same locally, but they have different global flag setters (which take the same parameters)
-
-List of misc manipulators:
-```
-YAML::Null;
-YAML::NewLine;  // print a blank line
-```
-
-List of comment manipulators:
-```
-YAML::Comment;
-YAML::Indent(int n);  // number of spaces to indent a comment after a value
-YAML::PostIndent(int n);  // number of spaces to indent the actual text of a comment after the '#' sign
-// e.g., with Indent(3) and PostIndent(2):
-// Hello   #  this is a comment

-# Basic Emitting #
-
-The model for emitting YAML is `std::ostream` manipulators. A `YAML::Emitter` objects acts as an output stream, and its output can be retrieved through the `c_str()` function (as in `std::string`). For a simple example:
-
-```
-#include "yaml-cpp/yaml.h"
-
-int main()
-{
-   YAML::Emitter out;
-   out << "Hello, World!";
-   
-   std::cout << "Here's the output YAML:\n" << out.c_str(); // prints "Hello, World!"
-   return 0;
-}
-```
-
-# Simple Lists and Maps #
-
-A `YAML::Emitter` object acts as a state machine, and we use manipulators to move it between states. Here's a simple sequence:
-
-```
-YAML::Emitter out;
-out << YAML::BeginSeq;
-out << "eggs";
-out << "bread";
-out << "milk";
-out << YAML::EndSeq;
-```
-produces
-```
-- eggs
-- bread
-- milk
-```
-
-A simple map:
-```
-YAML::Emitter out;
-out << YAML::BeginMap;
-out << YAML::Key << "name";
-out << YAML::Value << "Ryan Braun";
-out << YAML::Key << "position";
-out << YAML::Value << "LF";
-out << YAML::EndMap;
-```
-produces
-```
-name: Ryan Braun
-position: LF
-```
-
-These elements can, of course, be nested:
-```
-YAML::Emitter out;
-out << YAML::BeginMap;
-out << YAML::Key << "name";
-out << YAML::Value << "Barack Obama";
-out << YAML::Key << "children";
-out << YAML::Value << YAML::BeginSeq << "Sasha" << "Malia" << YAML::EndSeq;
-out << YAML::EndMap;
-```
-produces
-```
-name: Barack Obama
-children:
-  - Sasha
-  - Malia
-```
-
-# Using Manipulators #
-
-To deviate from standard formatting, you can use manipulators to modify the output format. For example,
-```
-YAML::Emitter out;
-out << YAML::Literal << "A\n B\n  C";
-```
-produces
-```
-|
-A
- B
-  C
-```
-and
-```
-YAML::Emitter out;
-out << YAML::Flow;
-out << YAML::BeginSeq << 2 << 3 << 5 << 7 << 11 < YAML::EndSeq;
-```
-produces
-```
-[2, 3, 5, 7, 11]
-```
-
-Comments act like manipulators:
-```
-YAML::Emitter out;
-out << YAML::BeginMap;
-out << YAML::Key << "method";
-out << YAML::Value << "least squares";
-out << YAML::Comment("should we change this method?");
-out << YAML::EndMap;
-```
-produces
-```
-method: least squares  # should we change this method?
-```
-
-And so do aliases/anchors:
-```
-YAML::Emitter out;
-out << YAML::BeginSeq;
-out << YAML::Anchor("fred");
-out << YAML::BeginMap;
-out << YAML::Key << "name" << YAML::Value << "Fred";
-out << YAML::Key << "age" << YAML::Value << "42";
-out << YAML::EndMap;
-out << YAML::Alias("fred");
-out << YAML::EndSeq;
-```
-produces
-```
-- &fred
-  name: Fred
-  age: 42
-- *fred
-```
-
-# STL Containers, and Other Overloads #
-We overload `operator <<` for `std::vector`, `std::list`, and `std::map`, so you can write stuff like:
-```
-std::vector <int> squares;
-squares.push_back(1);
-squares.push_back(4);
-squares.push_back(9);
-squares.push_back(16);
-
-std::map <std::string, int> ages;
-ages["Daniel"] = 26;
-ages["Jesse"] = 24;
-
-YAML::Emitter out;
-out << YAML::BeginSeq;
-out << YAML::Flow << squares;
-out << ages;
-out << YAML::EndSeq;
-```
-to produce
-```
-- [1, 4, 9, 16]
--
-  Daniel: 26
-  Jesse: 24
-```
-
-Of course, you can overload `operator <<` for your own types:
-```
-struct Vec3 { int x; int y; int z; };
-YAML::Emitter& operator << (YAML::Emitter& out, const Vec3& v) {
-	out << YAML::Flow;
-	out << YAML::BeginSeq << v.x << v.y << v.z << YAML::EndSeq;
-	return out;
-}
-```
-and it'll play nicely with everything else.
-
-# Using Existing Nodes #
-
-We also overload `operator << ` for `YAML::Node`s in both APIs, so you can output existing Nodes. Of course, Nodes in the old API are read-only, so it's tricky to emit them if you want to modify them. So use the new API!
-
-# Output Encoding #
-
-The output is always UTF-8. By default, yaml-cpp will output as much as it can without escaping any characters. If you want to restrict the output to ASCII, use the manipulator `YAML::EscapeNonAscii`:
-
-```
-emitter.SetOutputCharset(YAML::EscapeNonAscii);
-```
-
-# Lifetime of Manipulators #
-
-Manipulators affect the **next** output item in the stream. If that item is a `BeginSeq` or `BeginMap`, the manipulator lasts until the corresponding `EndSeq` or `EndMap`. (However, within that sequence or map, you can override the manipulator locally, etc.; in effect, there's a "manipulator stack" behind the scenes.)
-
-If you want to permanently change a setting, there are global setters corresponding to each manipulator, e.g.:
-```
-YAML::Emitter out;
-out.SetIndent(4);
-out.SetMapStyle(YAML::Flow);
-```
-
-# When Something Goes Wrong #
-
-If something goes wrong when you're emitting a document, it must be something like forgetting a `YAML::EndSeq`, or a misplaced `YAML::Key`. In this case, emitting silently fails (no more output is emitted) and an error flag is set. For example:
-
-```
-   YAML::Emitter out;
-   assert(out.good());
-   out << YAML::Key;
-   assert(!out.good());
-   std::cout << "Emitter error: " << out.GetLastError() << "\n";
-```

-
-## Contents ##
-
-
-# Basic Parsing #
-
-The parser accepts streams, not file names, so you need to first load the file. Since a YAML file can contain many documents, you can grab them one-by-one. A simple way to parse a YAML file might be:
-
-```
-#include <fstream>
-#include "yaml-cpp/yaml.h"
-
-int main()
-{
-    std::ifstream fin("test.yaml");
-    YAML::Parser parser(fin);
-
-    YAML::Node doc;
-    while(parser.GetNextDocument(doc)) {
-       // ...
-    }
-
-    return 0;
-}
-```
-
-# Reading From the Document #
-
-Suppose we have a document consisting only of a scalar. We can read that scalar like this:
-
-```
-YAML::Node doc;    // let's say we've already parsed this document
-std::string scalar;
-doc >> scalar;
-std::cout << "That scalar was: " << scalar << std::endl;
-```
-
-How about sequences? Let's say our document now consists only of a sequences of scalars. We can use an iterator:
-
-```
-YAML::Node doc;    // already parsed
-for(YAML::Iterator it=doc.begin();it!=doc.end();++it) {
-    std::string scalar;
-    *it >> scalar;
-    std::cout << "Found scalar: " << scalar << std::endl;
-}
-```
-
-... or we can just loop through:
-
-```
-YAML::Node doc;    // already parsed
-for(unsigned i=0;i<doc.size();i++) {
-    std::string scalar;
-    doc[i] >> scalar;
-    std::cout << "Found scalar: " << scalar << std::endl;
-}
-```
-
-And finally maps. For now, let's say our document is a map with all keys/values being scalars. Again, we can iterate:
-
-```
-YAML::Node doc;    // already parsed
-for(YAML::Iterator it=doc.begin();it!=doc.end();++it) {
-    std::string key, value;
-    it.first() >> key;
-    it.second() >> value;
-    std::cout << "Key: " << key << ", value: " << value << std::endl;
-}
-```
-
-Note that dereferencing a map iterator is undefined; instead, use the `first` and `second` methods to get the key and value nodes, respectively.
-
-Alternatively, we can pick off the values one-by-one, if we know the keys:
-
-```
-YAML::Node doc;    // already parsed
-std::string name;
-doc["name"] >> name;
-int age;
-doc["age"] >> age;
-std::cout << "Found entry with name '" << name << "' and age '" << age << "'\n";
-```
-
-One thing to be keep in mind: reading a map by key (as immediately above) requires looping through all entries until we find the right key, which is an O(n) operation. So if you're reading the entire map this way, it'll be O(n^2). For small n, this isn't a big deal, but I wouldn't recommend reading maps with a very large number of entries (>100, say) this way.
-
-## Optional Keys ##
-
-If you try to access a key that doesn't exist, `yaml-cpp` throws an exception (see [HowToParseADocument#When\_Something\_Goes\_Wrong](HowToParseADocument#When_Something_Goes_Wrong.md) When Something Goes Wrong). If you have optional keys, you it's often easier to use `FindValue` instead of `operator[]`:
-
-```
-YAML::Node doc;    // already parsed
-if(const YAML::Node *pName = doc.FindValue("name")) {
-    std::string name;
-    *pName >> name;
-    std::cout << "Key 'name' exists, with value '" << name << "'\n";
-} else {
-    std::cout << "Key 'name' doesn't exist\n";
-}
-```
-
-# Getting More Complicated #
-
-The above three methods can be combined to read from an arbitrary document. But we can make life a lot easier. Suppose we're reading 3-vectors (i.e., vectors with three components), so we've got a structure looking like this:
-
-```
-struct Vec3 {
-    float x, y, z;
-};
-```
-
-We can read this in one operation by overloading the extraction (>>) operator:
-
-```
-void operator >> (const YAML::Node& node, Vec3& v)
-{
-    node[0] >> v.x;
-    node[1] >> v.y;
-    node[2] >> v.z;
-}
-
-// now it's a piece of cake to read it
-YAML::Node doc;    // already parsed
-Vec3 v;
-doc >> v;
-std::cout << "Here's the vector: (" << v.x << ", " << v.y << ", " << v.z << ")\n";
-```
-
-# A Complete Example #
-
-Here's a complete example of how to parse a complex YAML file:
-
-`monsters.yaml`
-
-```
-- name: Ogre
-  position: [0, 5, 0]
-  powers:
-    - name: Club
-      damage: 10
-    - name: Fist
-      damage: 8
-- name: Dragon
-  position: [1, 0, 10]
-  powers:
-    - name: Fire Breath
-      damage: 25
-    - name: Claws
-      damage: 15
-- name: Wizard
-  position: [5, -3, 0]
-  powers:
-    - name: Acid Rain
-      damage: 50
-    - name: Staff
-      damage: 3
-```
-
-`main.cpp`
-
-```
-#include "yaml-cpp/yaml.h"
-#include <iostream>
-#include <fstream>
-#include <string>
-#include <vector>
-
-// our data types
-struct Vec3 {
-   float x, y, z;
-};
-
-struct Power {
-   std::string name;
-   int damage;
-};
-
-struct Monster {
-   std::string name;
-   Vec3 position;
-   std::vector <Power> powers;
-};
-
-// now the extraction operators for these types
-void operator >> (const YAML::Node& node, Vec3& v) {
-   node[0] >> v.x;
-   node[1] >> v.y;
-   node[2] >> v.z;
-}
-
-void operator >> (const YAML::Node& node, Power& power) {
-   node["name"] >> power.name;
-   node["damage"] >> power.damage;
-}
-
-void operator >> (const YAML::Node& node, Monster& monster) {
-   node["name"] >> monster.name;
-   node["position"] >> monster.position;
-   const YAML::Node& powers = node["powers"];
-   for(unsigned i=0;i<powers.size();i++) {
-      Power power;
-      powers[i] >> power;
-      monster.powers.push_back(power);
-   }
-}
-
-int main()
-{
-   std::ifstream fin("monsters.yaml");
-   YAML::Parser parser(fin);
-   YAML::Node doc;
-   parser.GetNextDocument(doc);
-   for(unsigned i=0;i<doc.size();i++) {
-      Monster monster;
-      doc[i] >> monster;
-      std::cout << monster.name << "\n";
-   }
-
-   return 0;
-}
-```
-
-# When Something Goes Wrong #
-
-... we throw an exception (all exceptions are derived from `YAML::Exception`). If there's a parsing exception (i.e., a malformed YAML document), we throw a `YAML::ParserException`:
-
-```
-try {
-    std::ifstream fin("test.yaml");
-    YAML::Parser parser(fin);
-    YAML::Node doc;
-    parser.GetNextDocument(doc);
-    // do stuff
-} catch(YAML::ParserException& e) {
-    std::cout << e.what() << "\n";
-}
-```
-
-If you make a programming error (say, trying to read a scalar from a sequence node, or grabbing a key that doesn't exist), we throw some kind of `YAML::RepresentationException`. To prevent this, you can check what kind of node something is:
-
-```
-    YAML::Node node;
-    YAML::NodeType::value type = node.Type();  // should be:
-                                               // YAML::NodeType::Null
-                                               // YAML::NodeType::Scalar
-                                               // YAML::NodeType::Sequence
-                                               // YAML::NodeType::Map
-```
-
-# Note about copying `YAML::Node` #
-
-Currently `YAML::Node` is non-copyable, so you need to do something like
-
-```
-    const YAML::Node& node = doc["whatever"];
-```
-
-This is intended behavior. If you want to copy a node, use the `Clone` function:
-
-```
-    std::auto_ptr<YAML::Node> pCopy = myOtherNode.Clone();
-```
-
-The intent is that if you'd like to keep a `YAML::Node` around for longer than the document will stay in scope, you can clone it and store it as long as you like.

-yaml-cpp uses [CMake](http://www.cmake.org) to support cross-platform building. The basic steps to build are:
-
-1. Download and install [CMake](http://www.cmake.org) (Resources -> Download).
-
-**Note:** If you don't use the provided installer for your platform, make sure that you add CMake's bin folder to your path.
-
-2. Navigate into the source directory, and type:
-
-```
-mkdir build
-cd build
-```
-
-3. Run CMake. The basic syntax is:
-
-```
-cmake [-G generator] [-DBUILD_SHARED_LIBS=ON|OFF] ..
-```
-
-  * The `generator` is whatever type of build system you'd like to use. To see a full list of generators on your platform, just run `cmake` (with no arguments). For example:
-    * On Windows, you might use "Visual Studio 9 2008" to generate a Visual Studio 2008 solution
-    * On OS X, you might use "Xcode" to generate an Xcode project
-    * On a UNIX-y system, simply omit the option to generate a makefile
-
-  * yaml-cpp defaults to building a static library, but you may build a shared library by specifying `-DBUILD_SHARED_LIBS=ON`.
-
-  * For more options on customizing the build, see the [CMakeLists.txt](http://code.google.com/p/yaml-cpp/source/browse/CMakeLists.txt) file.

-# Introduction #
-
-Understandably, the yaml-cpp management would like to keep the /trunk in a fairly reasonable state for consumers of the yaml-cpp library.  There are, however, occasions that arise where multiple patch branches that do not merge cleanly need to be integrated before they can be combined back into /trunk.  In these cases we fall back on staging branches.
-
-
-# Where Are the Staging Branches? #
-
-Staging branches, like other branches, are found in the project's Subversion repository under the /branches folder.  Anonymous access is available at
-http://yaml-cpp.googlecode.com/svn/branches.  The staging branches have the form _username_-staging.
-
-As of this writing, the only staging branch is http://yaml-cpp.googlecode.com/svn/branches/rtweeks21-staging, but please check the branches link (from the previous paragraph) for the latest information.
-
-
-# What is in a Staging Branch? #
-
-That is really up to the developer who owns the branch.  Staging branches will typically look like a copy of the HEAD of /trunk into which some other branches have been reintegrated.  Staging branches are intended to provide an area to prepare a group of (possibly unrelated) changes to go into the trunk.
-
-
-# How Will the Developers Keep Track of the Merges? #
-
-All Subversion clients starting with version 1.5 add information about merges between branches to appropriate folders in the svn:mergeinfo property.  These clients can therefore track (and report) which version have been merged from one branch to another and avoid any attempts to re-merge a revision.
-
-The best way to merge a feature or bug-fix branch into a staging branch (or a staging branch into /trunk) is `svn merge --reintegrate`, which will correctly handle changes from any synchronization merges from /trunk into the development branch.  This follows the procedure recommended by the Subversion documentation.

-# Encodings and `yaml-cpp` #
-
-`yaml-cpp` will parse any file as specificed by the [YAML 1.2 spec](http://www.yaml.org/spec/1.2/spec.html#id2570322). Internally, it stores all strings in UTF-8, and representation is done with UTF-8. This means that in
-
-```
-std::string str;
-node >> str;
-```
-
-`str` will be UTF-8. Similarly, if you're accessing a map by string key, you need to pass the key in UTF-8. If your application uses a different encoding, you need to convert to and from UTF-8 to work with `yaml-cpp`. (It's possible we'll add some small conversion functions, but for now it's restricted.)
-
-For convenience, Richard Weeks has kindly provided a google gadget that converts Unicode to a string literal. Just paste in the Unicode:

-# Introduction #
-
-_The following describes the new API. For the old API, see [HowToParseADocument](HowToParseADocument.md) or [HowToEmitYAML](HowToEmitYAML.md)._
-
-A typical example, loading a configuration file, might look like this:
-
-```
-YAML::Node config = YAML::LoadFile("config.yaml");
-
-if (config["lastLogin"]) {
-  std::cout << "Last logged in: " << config["lastLogin"].as<DateTime>() << "\n";
-}
-
-const std::string username = config["username"].as<std::string>();
-const std::string password = config["password"].as<std::string>();
-login(username, password);
-config["lastLogin"] = getCurrentDateTime();
-
-std::ofstream fout("config.yaml");
-fout << config;
-```
-
-# Basic Parsing and Node Editing #
-
-All nodes in a YAML document (including the root) are represented by `YAML::Node`. You can check what kind it is:
-
-```
-YAML::Node node = YAML::Load("[1, 2, 3]");
-assert(node.Type() == YAML::NodeType::Sequence);
-assert(node.IsSequence());  // a shortcut!
-```
-
-Collection nodes (sequences and maps) act somewhat like STL vectors and maps:
-
-```
-YAML::Node primes = YAML::Load("[2, 3, 5, 7, 11]");
-for (std::size_t i=0;i<primes.size();i++) {
-  std::cout << primes[i].as<int>() << "\n";
-}
-// or:
-for (YAML::const_iterator it=primes.begin();it!=primes.end();++it) {
-  std::cout << it->as<int>() << "\n";
-}
-
-primes.push_back(13);
-assert(primes.size() == 6);
-```
-
-and
-
-```
-YAML::Node lineup = YAML::Load("{1B: Prince Fielder, 2B: Rickie Weeks, LF: Ryan Braun}");
-for(YAML::const_iterator it=lineup.begin();it!=lineup.end();++it) {
-  std::cout << "Playing at " << it->first.as<std::string>() << " is " << it->second.as<std::string>() << "\n";
-}
-
-lineup["RF"] = "Corey Hart";
-lineup["C"] = "Jonathan Lucroy";
-assert(lineup.size() == 5);
-```
-
-Querying for keys does **not** create them automatically (this makes handling optional map entries very easy)
-
-```
-YAML::Node node = YAML::Load("{name: Brewers, city: Milwaukee}");
-if (node["name"]) {
-  std::cout << node["name"].as<std::string>() << "\n";
-}
-if (node["mascot"]) {
-  std::cout << node["mascot"].as<std::string>() << "\n";
-}
-assert(node.size() == 2); // the previous call didn't create a node
-```
-
-If you're not sure what kind of data you're getting, you can query the type of a node:
-
-```
-switch (node.Type()) {
-  case Null: // ...
-  case Scalar: // ...
-  case Sequence: // ...
-  case Map: // ...
-  case Undefined: // ...
-}
-```
-
-or ask directly whether it's a particular type, e.g.:
-
-```
-if (node.IsSequence()) {
-  // ...
-}
-```
-
-# Building Nodes #
-
-You can build `YAML::Node` from scratch:
-
-```
-YAML::Node node;  // starts out as null
-node["key"] = "value";  // it now is a map node
-node["seq"].push_back("first element");  // node["seq"] automatically becomes a sequence
-node["seq"].push_back("second element");
-
-node["mirror"] = node["seq"][0];  // this creates an alias
-node["seq"][0] = "1st element";  // this also changes node["mirror"]
-node["mirror"] = "element #1";  // and this changes node["seq"][0] - they're really the "same" node
-
-node["self"] = node;  // you can even create self-aliases
-node[node["mirror"]] = node["seq"];  // and strange loops :)
-```
-
-The above node is now:
-
-```
-&1
-key: value
-&2 seq: [&3 "element #1", second element]
-mirror: *3
-self: *1
-*3 : *2
-```
-
-# How Sequences Turn Into Maps #
-
-Sequences can be turned into maps by asking for non-integer keys. For example,
-
-```
-YAML::Node node  = YAML::Load("[1, 2, 3]");
-node[1] = 5;  // still a sequence, [1, 5, 3]
-node.push_back(-3) // still a sequence, [1, 5, 3, -3]
-node["key"] = "value"; // now it's a map! {0: 1, 1: 5, 2: 3, 3: -3, key: value}
-```
-
-Indexing a sequence node by an index that's not in its range will _usually_ turn it into a map, but if the index is one past the end of the sequence, then the sequence will grow by one to accommodate it. (That's the **only** exception to this rule.) For example,
-
-```
-YAML::Node node = YAML::Load("[1, 2, 3]");
-node[3] = 4; // still a sequence, [1, 2, 3, 4]
-node[10] = 10;  // now it's a map! {0: 1, 1: 2, 2: 3, 3: 4, 10: 10}
-```
-
-# Converting To/From Native Data Types #
-
-Yaml-cpp has built-in conversion to and from most built-in data types, as well as `std::vector`, `std::list`, and `std::map`. The following examples demonstrate when those conversions are used:
-
-```
-YAML::Node node = YAML::Load("{pi: 3.14159, [0, 1]: integers}");
-
-// this needs the conversion from Node to double
-double pi = node["pi"].as<double>();
-
-// this needs the conversion from double to Node
-node["e"] = 2.71828;
-
-// this needs the conversion from Node to std::vector<int> (*not* the other way around!)
-std::vector<int> v;
-v.push_back(0);
-v.push_back(1);
-std::string str = node[v].as<std::string>();
-```
-
-To use yaml-cpp with your own data types, you need to specialize the YAML::convert<> template class. For example, suppose you had a simple `Vec3` class:
-
-```
-struct Vec3 { double x, y, z; /* etc - make sure you have overloaded operator== */ };
-```
-
-You could write
-
-```
-namespace YAML {
-template<>
-struct convert<Vec3> {
-  static Node encode(const Vec3& rhs) {
-    Node node;
-    node.push_back(rhs.x);
-    node.push_back(rhs.y);
-    node.push_back(rhs.z);
-    return node;
-  }
-
-  static bool decode(const Node& node, Vec3& rhs) {
-    if(!node.IsSequence() || node.size() != 3) {
-      return false;
-    }
-
-    rhs.x = node[0].as<double>();
-    rhs.y = node[1].as<double>();
-    rhs.z = node[2].as<double>();
-    return true;
-  }
-};
-}
-```
-
-Then you could use `Vec3` wherever you could use any other type:
-
-```
-YAML::Node node = YAML::Load("start: [1, 3, 0]");
-Vec3 v = node["start"].as<Vec3>();
-node["end"] = Vec3(2, -1, 0);
-```

+*** With CMake ***
+
+yaml-cpp uses CMake to support cross-platform building. In a UNIX-like system, the basic steps to build are:
+
+1. Download and install CMake (if you don't have root privileges, just install to a local directory, like ~/bin)
+
+2. From the source directory, run:
+
+mkdir build
+cd build
+cmake ..
+
+and then the usual
+
+make
+make install
+
+3. To clean up, just remove the 'build' directory.
+
+*** Without CMake ***
+
+If you don't want to use CMake, just add all .cpp files to a makefile. yaml-cpp does not need any special build settings, so no 'configure' file is necessary.
+
+(Note: this is pretty tedious. It's sooo much easier to use CMake.)
