+The language-specific bindings (the code in `contrib/bindings/` and
+`go-pathrs/`) are licensed under the Apache-2.0 license, to allow for wider
+usage of `libpathrs` from languages where language libraries are not
+dynamically linked.

+**NOTE**: If you compile libpathrs.so into your binary statically, you still
+need to abide by the LGPLv3 license. In practice this means at least providing
+the object files necessary to allow someone to recompile your program using a
+modified libpathrs. See the LGPLv3 license for more details.
