directory re-organization (keeps the old build system)

there is no internal modification of any file in this commit

files are moved into directories according to established standards in
sourcecode distribution; these directories contain:

 src - Files that are used in constructing the executable binaries,
       but are not installed.

 doc - Files in HTML and text format that document usage, quirks of
       the implementation, and contributor checklists.

 locale - Files that contain human language translation of strings
          used in the program

 contrib - Files contributed from distributions or other third party
 	   implementing scripts and auxiliary programs

+WINDOWS BUILD NOTES
+===================
+
+Compilers Supported
+-------------------
+MinGW GCC  http://tdm-gcc.tdragon.net/
+   TDM-GCC with gcc 4.5.1 was used to build this release.
+MSYS 1.0.11 was also used (sh needed to compile some dependencies)
+
+
+Candidate releases were built with MSVC 10.0 (2010), but
+compiling with Visual C++ caused rendering artifacts when
+bitcoin was run.
+
+
+Dependencies
+------------
+Libraries you need to download separately and build:
+
+                default path               download
+wxWidgets       \wxwidgets-2.9.1-mgw       http://www.wxwidgets.org/downloads/
+OpenSSL         \openssl-1.0.0c-mgw        http://www.openssl.org/source/
+Berkeley DB     \db-4.7.25.NC-mgw          http://www.oracle.com/technology/software/products/berkeley-db/index.html
+Boost           \boost-1.43.0-mgw          http://www.boost.org/users/download/

+
+Their licenses:
+wxWidgets      LGPL 2.1 with very liberal exceptions
+OpenSSL        Old BSD license with the problematic advertising requirement
+Berkeley DB    New BSD license with additional requirement that linked software must be free open source
+Boost          MIT-like license
+miniupnpc      New (3-clause) BSD license
+
+Versions used in this release:
+wxWidgets    2.9.1
+OpenSSL      1.0.0c
+Berkeley DB  4.7.25.NC
+Boost        1.43.0
+miniupnpc    1.5-20110215
+
+
+Notes
+-----
+The UI layout is edited with wxFormBuilder.  The project file is
+uiproject.fbp.  It generates uibase.cpp and uibase.h, which define base
+classes that do the rote work of constructing all the UI elements.
+
+wxWidgets
+---------
+DOS shell:
+cd \wxWidgets-2.9.1-mgw\build\msw
+mingw32-make -f makefile.gcc
+
+OpenSSL
+-------
+MSYS shell:
+un-tar sources with MSYS 'tar xfz' to avoid issue with symlinks (OpenSSL ticket 2377)
+change 'MAKE' env. variable from 'C:\MinGW32\bin\mingw32-make.exe' to '/c/MinGW32/bin/mingw32-make.exe'
+
+cd /c/openssl-1.0.0c-mgw
+./config
+make
+
+perl util/mkdef.pl 32 libeay enable-static-engine > libeay32.def
+dllwrap --dllname libeay32.dll --output-lib libeay32.a --def libeay32.def libcrypto.a -lws2_32 -lgdi32
+
+after that openssl libeay is in main source dir (openssl-1.0.0c-mgw)
+
+Berkeley DB
+-----------
+MSYS shell:
+cd /c/db-4.7.25.NC-mgw/build_unix
+sh ../dist/configure --enable-mingw --enable-cxx
+make
+
+
+Boost
+-----
+DOS prompt:
+downloaded boost jam 3.1.18
+cd \boost-1.43.0-mgw
+bjam toolset=gcc --build-type=complete stage
+
+Note:
+building with boost 1.45.0 failed because of boost ticket 4614, 4258
+builds fine with boost 1.43.0
+
+MiniUPnPc
+---------
+Building miniupnpc failed on Windows Server 2003, thus it is expected that a binary copy will be used.
+See http://miniupnp.tuxfamily.org/forum/viewtopic.php?t=642
+UPnP support is optional, make with USE_UPNP= to disable it.
+
+Get upnpc-exe-win32-20110215.zip and unzip it to \upnpc-exe-win32-20110215
+Get miniupnpc-1.5.20110215.tar.gz and copy *.h to \upnpc-exe-win32-20110215\miniupnpc
+
+Bitcoin
+-------
+DOS prompt:
+cd \bitcoin\src
+mingw32-make bitcoin.exe bitcoind.exe -f makefile.mingw

+
+
+Mac OS X build instructions
+Laszlo Hanyecz (solar@heliacal.net)
+
+
+Tested on 10.5 and 10.6 intel.  PPC is not supported because it's big-endian.
+
+All of the commands should be executed in Terminal.app.. it's in
+/Applications/Utilities
+
+You need to install XCode with all the options checked so that the compiler
+and everything is available in /usr not just /Developer
+I think it comes on the DVD but you can get the current version from
+http://developer.apple.com
+
+
+1.  Pick a directory to work inside.. something like ~/bitcoin works.  The
+structure I use looks like this:
+(~ is your home directory)
+
+~/bitcoin
+~/bitcoin/trunk         # source code
+~/bitcoin/deps          # dependencies.. like libraries and headers needed to compile
+~/bitcoin/Bitcoin.app   # the application bundle where you can run the app
+
+Just execute: mkdir ~/bitcoin
+This will create the top dir for you..
+
+WARNING: do not use the ~ notation with the configure scripts.. use the full
+name of the directory, for example /Users/james/bitcoin/deps for a user named
+'james'.  In my examples I am using 'macosuser' so make sure you change that.
+
+2.  Check out the trunk version of the bitcoin code from subversion:
+
+cd ~/bitcoin
+svn checkout https://bitcoin.svn.sourceforge.net/svnroot/bitcoin/trunk
+
+This will make ~/bitcoin/trunk for you with all the files from subversion. 
+
+3.  Get and build the dependencies
+
+
+Boost
+-----
+
+Download from http://www.boost.org/users/download/
+I'm assuming it ended up in ~/Downloads..
+
+mkdir ~/bitcoin/deps
+cd ~/bitcoin/deps
+tar xvjf ~/Downloads/boost_1_42_0.tar.bz2
+cd boost_1_42_0
+./bootstrap.sh
+./bjam architecture=combined address-model=32_64 macosx-version=10.5 macosx-version-min=10.5 link=static runtime-link=static --toolset=darwin --prefix=/Users/macosuser/bitcoin/deps install
+
+If you're using Snow Leopard, you will need to specify 10.6 as your Mac OS X
+version instead of 10.5.
+
+This part takes a while.. use your judgement and fix it if something doesn't
+build for some reason.
+
+Change the prefix to whatever your directory is (my username in this example
+is macosuser).  I'm also running on 10.6 so i have macosx-version=10.6  change
+to 10.5 if you're using leopard.
+
+This is what my output looked like at the end:
+...failed updating 2 targets...
+...skipped 144 targets...
+...updated 8074 targets...
+
+
+OpenSSL
+-------
+
+Download from http://www.openssl.org/source/
+
+We would like to build this as a 32 bit/64 bit library so we actually build it
+2 times and join it together here..  If you downloaded with safari it already
+uncompressed it so it will just be a tar not a tar.gz
+
+cd ~/bitcoin/deps
+tar xvf ~/Downloads/openssl-1.0.0.tar
+mv openssl-1.0.0 openssl-1.0.0-i386
+tar xvf ~/Downloads/openssl-1.0.0.tar

+cd ..
+# build x86_64 (64 bit intel) binary
+cd openssl-1.0.0-x86_64

+
+Verify your binaries
+
+file lib/libcrypto.a
+
+output should look like this:
+
+lib/libcrypto.a: Mach-O universal binary with 2 architectures
+lib/libcrypto.a (for architecture i386):	current ar archive random library
+lib/libcrypto.a (for architecture x86_64):	current ar archive random library
+
+
+miniupnpc
+---------
+
+The process for miniupnpc (optional) is similar to that of OpenSSL.
+
+Download from http://miniupnp.tuxfamily.org/files/.
+
+cd ~/bitcoin/deps
+tar xvf ~/Downloads/miniupnpc-1.5.tar
+mv miniupnpc-1.5 miniupnpc-1.5-x86_64
+tar xvf ~/Downloads/miniupnpc-1.5.tar

+
+Verify your binaries
+
+file lib/libminiupnpc.a
+
+output should look like this:
+
+lib/libminiupnpc.a: Mach-O universal binary with 2 architectures
+lib/libminiupnpc.a (for architecture i386):	current ar archive random library
+lib/libminiupnpc.a (for architecture x86_64):	current ar archive random library
+
+
+Berkeley DB
+-----------
+
+Download from http://freshmeat.net/projects/berkeleydb/
+
+cd ~/bitcoin/deps
+tar xvf ~/Downloads/db-4.8.26.tar
+cd db-4.8.26/build_unix
+../dist/configure --prefix=/Users/macosuser/bitcoin/deps --enable-cxx && make && make install
+
+
+wxWidgets
+---------
+
+This is the big one..
+
+Check it out from svn
+
+cd ~/bitcoin/deps
+svn checkout http://svn.wxwidgets.org/svn/wx/wxWidgets/trunk wxWidgets-trunk
+
+This will make a wxWidgets-trunk directory in deps.
+
+Use this script snippet, change your prefix to whatever your dir is:
+
+PREFIX=~/bitcoin/deps
+SRCDIR="$PREFIX/wxWidgets-trunk"
+BUILDDIR="$SRCDIR/macbuild"
+
+cd "$PREFIX" &&
+#svn checkout http://svn.wxwidgets.org/svn/wx/wxWidgets/trunk wxWidgets-trunk &&
+cd "$SRCDIR" &&
+
+[ -f include/wx/hashmap.h.orig ] || cp include/wx/hashmap.h include/wx/hashmap.h.orig &&
+sed 's/if wxUSE_STL/if 0 \&\& wxUSE_STL/g' < include/wx/hashmap.h.orig > include/wx/hashmap.h &&
+
+[ -f include/wx/hashset.h.orig ] || cp include/wx/hashset.h include/wx/hashset.h.orig &&
+sed 's/if wxUSE_STL/if 0 \&\& wxUSE_STL/g' < include/wx/hashset.h.orig > include/wx/hashset.h &&
+
+
+
+rm -vrf "$BUILDDIR" &&
+mkdir "$BUILDDIR" &&
+cd "$BUILDDIR" &&
+
+../configure --prefix="$PREFIX" \
+--with-osx_cocoa \
+--disable-shared \
+--disable-debug_flag \
+--with-macosx-version-min=10.5 \
+--enable-stl \
+--enable-utf8 \
+--enable-universal_binary \
+--with-libjpeg=builtin \
+--with-libpng=builtin \
+--with-regex=builtin \
+--with-libtiff=builtin \
+--with-zlib=builtin \
+--with-expat=builtin \
+--with-macosx-sdk=/Developer/SDKs/MacOSX10.5.sdk &&
+
+
+find . -name Makefile | 
+while read i; do 
+  echo $i; 
+  sed 's/-arch i386/-arch i386 -arch x86_64/g' < "$i" > "$i".new && 
+  mv "$i" "$i".old && 
+  mv "$i".new "$i"; 
+done
+
+
+
+make && 
+make install
+
+
+
+Now you should be able to build bitcoin
+
+cd ~/bitcoin/trunk
+make -f makefile.osx bitcoin
+
+Before you can run it, you need to create an application bundle for Mac OS.
+Create the directories in terminal using mkdir and copy the files into place.
+They are available at http://heliacal.net/~solar/bitcoin/mac-build/
+You need the Info.plist and the .ins file.  The Contents/MacOS/bitcoin file is
+the output of the build.
+Your directory structure should look like this:
+
+Bitcoin.app
+Bitcoin.app/Contents
+Bitcoin.app/Contents/Info.plist
+Bitcoin.app/Contents/MacOS
+Bitcoin.app/Contents/MacOS/bitcoin
+Bitcoin.app/Contents/Resources
+Bitcoin.app/Contents/Resources/BitcoinAppIcon.icns
+
+To run it you can just click the Bitcoin.app in Finder, or just do open
+~/bitcoin/Bitcoin.app
+If you want to run it with arguments you can just run it without backgrounding
+by specifying the full name in terminal:
+~/bitcoin/Bitcoin.app/Contents/MacOS/bitcoin -addnode=192.75.207.66

+UNIX BUILD NOTES
+================
+
+To Build
+--------
+
+cd src/
+
+make -f makefile.unix            # Bitcoin with wxWidgets GUI
+  or
+make -f makefile.unix bitcoind   # Headless bitcoin
+
+
+Dependencies
+------------
+sudo apt-get install build-essential
+sudo apt-get install libgtk2.0-dev
+sudo apt-get install libssl-dev
+sudo apt-get install libdb4.7-dev
+sudo apt-get install libdb4.7++-dev
+Boost 1.40+: sudo apt-get install libboost-all-dev
+or Boost 1.37: sudo apt-get install libboost1.37-dev
+
+If using Boost 1.37, append -mt to the boost libraries in the makefile.
+
+Requires wxWidgets 2.9.0 or greater, which uses UTF-8.  Don't try 2.8, it
+won't work.
+
+You need to download wxWidgets from http://www.wxwidgets.org/downloads/
+and build it yourself.  See the build instructions and configure parameters
+below.
+
+Requires miniupnpc for UPnP port mapping.  To compile with UPnP support,
+install miniupnpc and compile after setting USE_UPNP.  It can be downloaded
+from http://miniupnp.tuxfamily.org/files/.  
+
+Licenses of statically linked libraries:
+wxWidgets      LGPL 2.1 with very liberal exceptions
+Berkeley DB    New BSD license with additional requirement that linked software must be free open source
+Boost          MIT-like license
+miniupnpc      New (3-clause) BSD license
+
+Versions used in this release:
+GCC          4.3.3
+OpenSSL      0.9.8g

+The UI layout is edited with wxFormBuilder.  The project file is
+uiproject.fbp.  It generates uibase.cpp and uibase.h, which define base
+classes that do the rote work of constructing all the UI elements.
+
+The release is built with GCC and then "strip bitcoin" to strip the debug
+symbols, which reduces the executable size by about 90%.
