If the default "make" is not GNU make (like in BSD systems), use "gmake"
instead. If the default "install" is not GNU/BSD compatible (like in Solaris
systems), use "gmake INSTALL=ginstall".


Special builds
--------------

 - To build with debugging information: "make DEBUG=1".
 - To build with profiling support: "make PROFILE=1".
 - To build with fault injection support, if you have libfiu: "make FI=1".


Python bindings
---------------

The library comes with bindings for Python 2 and Python 3. In order to build
them, you should have libjio already installed.
