+https://github.com/google/double-conversion/
+
+This project (double-conversion) provides binary-decimal and decimal-binary
+routines for IEEE doubles.
+
+The library consists of efficient conversion routines that have been extracted
+from the V8 JavaScript engine. The code has been refactored and improved so that
+it can be used more easily in other projects.
+
+There is extensive documentation in double-conversion/double-conversion.h. Other 
+examples can be found in test/cctest/test-conversions.cc.
+
+
+Building
+========
+
+This library can be built with scons [0] or cmake [1].
+The checked-in Makefile simply forwards to scons, and provides a
+shortcut to run all tests:
+
+    make
+    make test
+
+Scons
+-----
+
+The easiest way to install this library is to use `scons`. It builds
+the static and shared library, and is set up to install those at the
+correct locations:
+
+    scons install
+
+Use the `DESTDIR` option to change the target directory:
+
+    scons DESTDIR=alternative_directory install
+
+Cmake
+-----
+
+To use cmake run `cmake .` in the root directory. This overwrites the
+existing Makefile.
+
+Use `-DBUILD_SHARED_LIBS=ON` to enable the compilation of shared libraries.
+Note that this disables static libraries. There is currently no way to
+build both libraries at the same time with cmake.
+
+Use `-DBUILD_TESTING=ON` to build the test executable.
+
+    cmake . -DBUILD_TESTING=ON
+    make
+    test/cctest/cctest --list | tr -d '<' | xargs test/cctest/cctest
