+
+  If you are using cmake directly, just add the flag
+  "-DCMAKE_TOOLCHAIN_FILE=/path/to/toolchain-file" when
+  running cmake.
+
+Using cmake directly:
+  cd ~/your-node-source-dir
+  mkdir name-of-build-dir     (can be anything)
+  cd name-of-build-dir
+  cmake ..
+
+  At this point you have generated a set of Makefiles and can use the standard
+  make commands (make, make install, etc.). The Makefile.cmake file is just a
+  wrapper around these commands; take a look at it for more details.
+
+Other build targets:
+  make Experimental
+  make Nightly
+  make NightlyMemoryCheck
+  make Continuous
+
+Additional options:
+  In the CMakeLists.txt, you'll see things like
+  option(SHARED_V8, ...). If you want to enable any of those options you can
+  pass "-DOPTION=True" when running cmake (e.g., cmake -DSHARED_V8=True).

-Major features planned: (somewhat ordered)
+- fix tests for NODE_MODULE_CONTEXTS=1
+- readline
+  - fix for two column glyphs. use Markus Kuhn's wcwidth.c
+  - fix for commands that extend beyond term width
+- Erradicate all traces of 'binary' encoding. Only used, now, in OpenSSL
+  binding.
+- EventSource branch merged
+- Use C++ style casts everywhere.
+- Ruby-like Process#detach (is that possible?)
+- stderr isn't flushing on exit
+- ReadStream should not use an offset in calls to fs.read
+  (so that it can pull in files larger than 2G)
+- process object should be defined in src/node.js not in c++
+- Test for EMFILE accept spin bug.
+- Deprecate setEncoding() and instead add option to on('data').
+  Example:
 
-- C++ API for external modules/plugins
-  (Some sort of module build system?)
+    stdin.on('data', { encoding: 'utf8' }, function (chunk) {
+      process.stdout.write('WRITE: ' + chunk);
+    });
 
-- Posgres module
-  (http://www.postgresql.org/docs/8.1/static/libpq-async.html)
+  Perhaps by assigning cb.opts.encoding and calling
+  EventEmitter.optHandlers.encoding() if it exists.
 
-- Support AF_UNIX named pipes
+- DOCS
+  - anchor links next to each function, for easy linking.
+    EG <a href="#fs.stat">#</a>
 
-- Signal handlers
-
-- Internally replace getaddrinfo() with udns
-  http://www.corpit.ru/mjt/udns.html
-  JS resolver interface
-
-- TLS
-
-- UDP interface
-
-- Socket pairs
+- "node --raw-js script.js" should bipass all Node code and load a raw V8
+  interpreter
+- Use http_parser_execute2() in node_http_parser.cc and make req.pause()
+  work correctly
+  https://github.com/ry/http-parser/blob/c95a5479596e95b7cdd88ca9d7b32fd3afb4379c/http_parser.h#L266

+- Implement setenv / unsetenv
+
+- Implement other stuff missing in node.cc/process
+  Like getuid, getgid, setgid, kill etc.
+
+- Better `net` support
+  * getaddrinfo
+  * setMulticastTTL, setMembership, setLoopback
+  * pipe, socketpair
+  * A named pipe should be provided when a unix socket is requested.
+  * SendMsg and RecvMsg should be supported with named pipes.
+
+- New libev backend
+  The current libev backend supports sockets only. This complicates stuff like
+  child processes, stdio. Best would be if node_net switched from exposing
+  readyness notifications to using completion notifications, so on windows we
+  could use IOCP for sockets. Experts tell me that is really the fastest way
+  to work with sockets on windows.
+
+- Child process issues
+  * Communication between parent and child is slow; it uses a socketpair
+    where a pipe would be much faster. Replace it by a pipe when there
+    is a libev backend that supports waiting for a pipe.
+  * When a child process spawns the pid is not available straightaway.
+    On linux the pid is available immediately because fork() doesn't
+    block; on windows a libeio thread is used to call CreateProcess.
+    So this can't really be fixed, but it could be worked around by adding a
+    'spawn' or 'pid' event.
+  * passing socket custom_fds is not supported
+  * child_process.exec() only works on systems with msys installed.
+    It's because it relies on the 'sh' shell. The default windows shell
+    is 'cmd' and it works a little differently. Maybe add an option to
+    specify the shell to exec()?
+
+- Make colorful util.inspect work on windows.
+
+- Stdio: support passing sockets between master/child process
+  Normal windows applications wouldn't like this, but it can be useful for
+  communication between node processes. This requires 
+  stdio.isStdinBlocking/isStdoutBlocking to be smarter.
+
+- Skip/fix tests that can never pass on windows
+
+- Find a solution for fs.symlink / fs.lstat / fs.chown
+  Windows has different symlink types: file symlinks (vista+),
+  directory symlinks (vista+), junction points (xp+) 
+
+- Handle _open_osfhandle failures
+  E.g. currently we're using the construct _open_osfhandle(socket/open/accept(...)).
+  Now socket() can fail by itself and _open_osfhandle can fail by itself too.
+  If socket() fails it returns -1 so _open_osfhandle fails as well, but and we'll always return/throw EBADF.
+  If _open_osfhandle fails but socket doesn't, a stray handle is left open. It should be fixed.
+
+- Think about `make install`
+
+- Extensions
+  Should be DLLs on windows.
+
+- Link pthreads-w32 statically by default
+
+- Link Mingw libraries statically by default
+  Like libstdc++.dll, more maybe.
+  Microsoft libs are always there, no static linkage required (e.g. msvcrt, winsock2).
+
+- Make (open?)SSL work
+
+- Support using shared libs (libeio, v8, c-ares)
+  Need to link with with a stub library. Libraries should use `dllexport`,
+  headers must have `dllimport`.
+
+- V8: push MINGW32 build fixes upstream
+
+- Work around missing pread/pwrite more elegantly
+  Currently it's exported from libeio, while it wasn't intended to be exported.
+  The libeio workaround implementation sucks, it uses a global mutex.
+  It should be possible to implement pread and pwrite using winapi's ReadFile/Writefile
+  directly, passing an OVERLAPPED structure while not associating with an completion port.
+
+- Work around missing inet_pton/inet_ntop more elegantly
+  Currently it's exported from from c-ares, while it wasn't intended to be exported.
+  It prevents linking c-ares dynamically. 
+
+- See what libev/libeio changes can be pushed upstream
+
+- 64-bit build
+  Should be possible with MinGW-w64, it's pretty good.
+
+- ... much more probably

+Major changes since:

+
+Major changes in release 1.1.1:
+* ares should now compile as C++ code (no longer uses reserved word
+  "class").
+* Added SRV support to adig test program.
+* Fixed a few error handling bugs in query processing.
+
+Major changes in release 1.1.0:
+* Added ares_free_string() function so that memory can be freed in the
+  same layer as it is allocated, a desirable feature in some
+  environments.
+* A few of the ares_dns.h macros are fixed to use the proper bitwise
+  operator.
+* Fixed a couple of fenceposts fixed in ares_expand_name()'s
+  bounds-checking.
+* In process_timeouts(), extract query->next before calling
+  next_server() and possibly freeing the query structure.
+* Casted arguments to ctype macros casted to unsigned char, since not
+  all char values are valid inputs to those macros according to ANSI.

+c-ares
+======
+
+This is c-ares, an asynchronous resolver library.  It is intended for
+applications which need to perform DNS queries without blocking, or need to
+perform multiple DNS queries in parallel.  The primary examples of such
+applications are servers which communicate with multiple clients and programs
+with graphical user interfaces.
+
+The full source code is available in the 'c-ares' release archives, and in a
+git repository: http://github.com/bagder/c-ares
+
+If you find bugs, correct flaws, have questions or have comments in general in
+regard to c-ares (or by all means the original ares too), get in touch with us
+on the c-ares mailing list: http://cool.haxx.se/mailman/listinfo/c-ares
+
+c-ares is of course distributed under the same MIT-style license as the
+original ares.
+
+You'll find all c-ares details and news here:
+
+        http://c-ares.haxx.se/
+
+
+NOTES FOR C-ARES HACKERS
+
+The following notes apply to c-ares version 1.7.0 and later.
+
+* The distributed ares_build.h file is only intended to be used on systems
+  which can not run the also distributed configure script.
+
+* The distributed ares_build.h file is generated as a copy of ares_build.h.dist
+  when the c-ares source code distribution archive file is originally created.
+
+* If you check out from git on a non-configure platform, you must run the
+  appropriate buildconf* script to set up ares_build.h and other local files
+  before being able of compiling the library.
+
+* On systems capable of running the configure script, the configure process
+  will overwrite the distributed ares_build.h file with one that is suitable
+  and specific to the library being configured and built, this new file is
+  generated from the ares_build.h.in template file.
+
+* If you intend to distribute an already compiled c-ares library you _MUST_
+  also distribute along with it the generated ares_build.h which has been
+  used to compile it. Otherwise the library will be of no use for the users of
+  the library that you have built. It is _your_ responsibility to provide this
+  file. No one at the c-ares project can know how you have built the library.
+
+* File ares_build.h includes platform and configuration dependent info,
+  and must not be modified by anyone. Configure script generates it for you.
+
+* We cannot assume anything else but very basic compiler features being
+  present. While c-ares requires an ANSI C compiler to build, some of the
+  earlier ANSI compilers clearly can't deal with some preprocessor operators.
+
+* Newlines must remain unix-style for older compilers' sake.
+
+* Comments must be written in the old-style /* unnested C-fashion */

+c-ares
+======
+
+This package is based on ares 1.1.1 (written by Greg Hudson). I decided to
+fork and release a separate project since the ares author didn't want the
+improvements that were vital for our use of it.
+
+This package is dubbed 'c-ares' since I (Daniel Stenberg) wanted this for use
+within the curl project (hence the letter C) and it makes a nice pun. Also,
+c-ares is not API compatible with ares: a new name makes that more obvious to
+the public.
+
+The original libares was distributed at athena-dist.mit.edu:pub/ATHENA/ares.

+
+                How to build c-ares using MSVC or Visual Studio
+               =================================================
+
+
+
+  How to build using MSVC from the command line
+  ---------------------------------------------
+
+  Open a command prompt window and ensure that the environment is properly
+  set up in order to use MSVC or Visual Studio compiler tools.
+
+  Change to c-ares source folder where Makefile.msvc file is located and run:
+
+  > nmake -f Makefile.msvc
+
+  This will build all c-ares libraries as well as three sample programs.
+
+  Once the above command has finished a new folder named MSVCXX will exist
+  below the folder where makefile.msvc is found. The name of the folder
+  depends on the MSVC compiler version being used to build c-ares.
+
+  Below the MSVCXX folder there will exist four folders named 'cares',
+  'ahost', 'acountry', and 'adig'. The 'cares' folder is the one that
+  holds the c-ares libraries you have just generated, the other three
+  hold sample programs that use the libraries.
+
+  The above command builds four versions of the c-ares library, dynamic
+  and static versions and each one in release and debug flavours. Each
+  of these is found in folders named dll-release, dll-debug, lib-release,
+  and lib-debug, which hang from the 'cares' folder mentioned above. Each
+  sample program also has folders with the same names to reflect which
+  library version it is using.
+
+
+  How to build using Visual Studio 6 IDE
+  --------------------------------------
+
+  A VC++ 6.0 reference workspace (vc6aws.dsw) is available within the 'vc'
+  folder to allow proper building of the library and sample programs.
+
+  1) Open the vc6aws.dsw workspace with MSVC6's IDE.
+  2) Select 'Build' from top menu.
+  3) Select 'Batch Build' from dropdown menu.
+  4) Make sure that the sixteen project configurations are 'checked'.
+  5) Click on the 'Build' button.
+  6) Once the sixteen project configurations are built you are done.
+
+  Dynamic and static c-ares libraries are built in debug and release flavours,
+  and can be located each one in its own subdirectory, dll-debug, dll-release,
+  lib-debug and lib-release, all of them below the 'vc\cares' subdirectory.
+
+  In the same way four executable versions of each sample program are built,
+  each using its respective library. The resulting sample executables are
+  located in its own subdirectory, dll-debug, dll-release, lib-debug and
+  lib-release, below the 'vc\acountry', 'vc\adig' and 'vc\ahost'folders.
+
+  These reference VC++ 6.0 configurations are generated using the dynamic CRT.
+
+
+  How to build using Visual Studio 2003 or newer IDE
+  --------------------------------------------------
+
+  First you have to convert the VC++ 6.0 reference workspace and project files
+  to the Visual Studio IDE version you are using, following next steps:
+
+  1) Open vc\vc6aws.dsw with VS20XX.
+  2) Allow VS20XX to update all projects and workspaces.
+  3) Save ALL and close VS20XX.
+  4) Open vc\vc6aws.sln with VS20XX.
+  5) Select batch build, check 'all' projects and click 'build' button.
+
+  Same comments relative to generated files and folders as done above for
+  Visual Studio 6 IDE apply here.
+
+
+  Relationship between c-ares library file names and versions
+  -----------------------------------------------------------
+
+  c-ares static release library version files:
+
+      libcares.lib -> static release library
+
+  c-ares static debug library version files:
+
+      libcaresd.lib -> static debug library
+
+  c-ares dynamic release library version files:
+
+      cares.dll -> dynamic release library
+      cares.lib -> import library for the dynamic release library
+      cares.exp -> export file for the dynamic release library
+
+  c-ares dynamic debug library version files:
+
+      caresd.dll -> dynamic debug library
+      caresd.lib -> import library for the dynamic debug library
+      caresd.exp -> export file for the dynamic debug library
+      caresd.pdb -> debug symbol file for the dynamic debug library
+
+
+  How to use c-ares static libraries
+  ----------------------------------
+
+  When using the c-ares static library in your program, you will have to
+  define preprocessor symbol CARES_STATICLIB while building your program,
+  otherwise you will get errors at linkage stage.
+
+
+Have Fun!
