+libclipboard [![Linux/OS X Build Status](https://travis-ci.org/jtanx/libclipboard.svg?branch=master)](https://travis-ci.org/jtanx/libclipboard) [![Win32 Build status](https://ci.appveyor.com/api/projects/status/r1oanfx5kd18xfxa?svg=true)](https://ci.appveyor.com/project/jtanx/libclipboard)
+=========
+
+A cross-platform clipboard library.
+
+## Currently supported actions
+* Checking clipboard data ownership
+* Clearing clipboard
+* Retrieving/setting text (UTF-8)
+
+## Supported platforms
+* Windows
+* Linux (X11)
+* OS X (Cocoa)
+
+## Platforms to be supported in the future
+* Linux (Wayland) (maybe)
+
+## Requirements
+* cmake
+* gtest & g++ >= 4.7 (optional; for unit testing)
+* libxcb-dev (for Linux/X11)
+* pthreads (for Linux/X11)
+
+## Building
+Quickstart
+~~~~~
+git clone https://github.com/jtanx/libclipboard
+cd libclipboard
+cmake .
+make -j4
+sudo make install        (optional)
+~~~~~
+
+Building test module and samples
+~~~~~
+cd libclipboard
+git submodule init
+git submodule update
+git clean -dxf            (if you had a previous build)
+cmake .
+make check -j4
+~~~~~
+
+To add SOVERSION to the library (i.e. `libclipboard.so.1`), configure with
+~~~~~
+cmake -DLIBCLIPBOARD_ADD_SOVERSION=ON
+~~~~~
+
+To build a shared library instead of a static library
+~~~~~
+cmake -DBUILD_SHARED_LIBS=ON
+~~~~~
+
+To build the library using the stdcall calling convention
+~~~~~
+cmake -DLIBCLIPBOARD_USE_STDCALL=on
+~~~~~
+
+To force the build of a particular backend, choose one of
+~~~~~
+cmake -DLIBCLIPBOARD_FORCE_WIN32=on
+cmake -DLIBCLIPBOARD_FORCE_X11=on
+cmake -DLIBCLIPBOARD_FORCE_COCOA=on
+~~~~~
+
+Note: This setting has only been tested for compiling the X11 backend on Windows.
+
+To uninstall
+~~~~~
+sudo make uninstall
+~~~~~
