 Usually (following most linux distribution's conventions), shared libraries produced by a project `name` of version `M.m.p` are named `libname.M.m.p`. However, since when accessing shared libraries through the JVM, only the `name` can be specified and no particular version, the convention adopted by flow is to append `M` to the library name and always keep the major version at zero.
