+A note on licensing
+-----------------------
+This library changed from the LGPLv3 to MPLv2 as a result of LGPL's requirements for freedom of source on static linking which rustc does.
+
+I've chosen to use the MPL as it is a weaker but still copyleft license that allows you to statically link.
+
+The MPL applies retroactively to all previous versions of this library and will be used for all future versions.
