Cleaning up

By default sys/ puts everything under /usr. Just to make things easier There are several reasons for this, but it may polute your system if you install multiple versions of r2 or use the one contained in the package system of your distro. If you want to remove previous installations of r2 from a specific directory type the following commands: $ ./configure --prefix=/usr/local $ make purge The purge will remove all r2 files from current and previous installations (older versions of it) from the /usr/local directory.
