+- Mac OS X       - Maintenance

-
-
-Testing
--------
-
-First, build it.
-
-On Ubuntu/Debian based
-* sudo apt-get install libboost-dev libboost-filesystem-dev libboost-program-options-dev libboost-regex-dev libcrypto++-dev libboost-date-time-dev
-* $ cd i2pd
-* $ make
-
-Then, run it:
-
-$ ./i2p
-
-The client should now reseed by itself.
-
-To visit an I2P page, you need to find the b32 address of your destination.
-After that, go to the webconsole and add it behind the url. (Remove http:// from the address)
-
-This should resulting in for example:
-http://localhost:7070/4oes3rlgrpbkmzv4lqcfili23h3cvpwslqcfjlk6vvguxyggspwa.b32.i2p
-
-
-Cmdline options
----------------
-
-* --host=               - The external IP (deprecated). 
-* --port=               - The port to listen on
-* --httpport=           - The http port to listen on
-* --log=                - Enable or disable logging to file. 1 for yes, 0 for no.
-* --daemon=             - Enable or disable daemon mode. 1 for yes, 0 for no.
-* --service=            - 1 if uses system folders (/var/run/i2pd.pid, /var/log/i2pd.log, /var/lib/i2pd).
-* --v6=                 - 1 if supports communication through ipv6, off by default
-* --floodfill=          - 1 if router is floodfill, off by default
-* --bandwidth=          - L if bandwidth is limited to 32Kbs/sec, O if not. Always O if floodfill, otherwise L by default.
-* --httpproxyport=      - The port to listen on (HTTP Proxy)
-* --socksproxyport=     - The port to listen on (SOCKS Proxy)
-* --proxykeys=          - optional keys file for proxy's local destination
-* --ircport=            - The local port of IRC tunnel to listen on. 6668 by default
-* --ircdest=            - I2P destination address of IRC server. For example irc.postman.i2p
-* --irckeys=            - optional keys file for tunnel's local destination 
-* --eepkeys=            - File name containing destination keys, for example privKeys.dat.
-                          The file will be created if it does not already exist (issue #110).
-* --eephost=            - Address incoming trafic forward to. 127.0.0.1 by default

-Building i2pd for Windows
-=========================
-
-Requirements for building:
-
-* Visual Studio 2013 (tested with VS2013 Update 1, Update 3, and Update 4)
-* Boost (tested with 1.56, 1.57, and 1.58)
-* Crypto++ (tested with 5.6.2)
-
-
-Building Boost (32-bit)
------------------------
-
-Open a Visual Studio x86 command prompt and run the following:
-
-	cd C:\path\to\boost\sources
-	bootstrap
-	b2 toolset=msvc-12.0 --build-type=complete --libdir=C:\Boost\lib\Win32 install --with-filesystem --with-program_options --with-regex --with-date_time
-
-
-Building Boost (64-bit)
------------------------
-
-Open a Visual Studio x64 command prompt and run the following:
-
-	cd C:\path\to\boost\sources
-	bootstrap
-	b2 toolset=msvc-12.0 --build-type=complete --libdir=C:\Boost\lib\x64 architecture=x86 address-model=64 install --with-filesystem --with-program_options --with-regex --with-date_time
-
-After Boost is compiled, set the environment variable `BOOST` to the directory
-Boost was installed to. If you followed the instructions outlined here, you
-should set it to `C:\Boost`. Additionally, set the BOOSTVER variable to the
-version of Boost that you're using, but instead of a '.' use a '_'. For
-example, I have `BOOSTVER` set to `1_58`.
-
-Building Crypto++
------------------
-
-* Open the crypttest Solution in VS2013
-* Visual Studio will ask to update the Solution/Project. Allow it.
-* Build the `cryptopp` project, both the Debug and Release targets and for both
-  Win32 and x64.
-* Create a folder called `cryptopp` in the crypto++ source directory, then copy
-  the header files to this new directory.
-* Set the `CRYPTOPP` environment variable pointing to the Crypto++ source directory.
-
-
-Building i2pd
--------------
-
-## Prep work ##
-
-I strongly advise setting up your own `INCLUDES` and `LIBS` instead of relying
-on the settings in the i2pd project file. By using your own settings, if the
-i2pd devs change the paths in the project file, your builds will still work.
-
-To do this, create or edit the file
-`%localappdata%\Microsoft\MSBuild\v4.0\Microsoft.Cpp.Win32.user`.
-
-For comparison, my file is reproduced below:
-
-	<?xml version="1.0" encoding="utf-8"?>
-	<Project DefaultTargets="Build" ToolsVersion="12.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
-	  <ImportGroup Label="PropertySheets">
-	  </ImportGroup>
-	  <PropertyGroup Label="UserMacros" />
-	  <PropertyGroup>
-	    <LibraryPath>$(CRYPTOPP)\$(Platform)\Output\$(Configuration);$(BOOST)\lib\$(Platform);$(LibraryPath)</LibraryPath>
-	    <IncludePath>$(CRYPTOPP);$(BOOST)\include\boost-$(BOOSTVER);$(IncludePath)</IncludePath>
-	  </PropertyGroup>
-	  <ItemDefinitionGroup />
-	  <ItemGroup />
-	</Project>
-
-
-If you want to build x64 binaries as well, you'll want to edit or create the
-file `%localappdata%\Microsoft\MSBuild\v4.0\Microsoft.Cpp.x64.user`. If you
-followed the steps outlined earlier you can copy (or link) the win32 file to
-the x64 one.
-
-## Anti-Climatic End ##
-
-After following the above instructions, you'll be able to build Debug Win32,
-Debug x64, Release Win32, and Release x64 i2pd binaries.
