Waf installation is optional and there are many advantages of not installing Waf, among them:
If, despite the advantages enumerated previously, you really want to install the Waf application on the system, you may use the following command on Unix-like systems such as Linux:
# ./waf-light configure --prefix=/usr/ # ./waf-light install
Root privileges may be required depending on the final location.
Waf can be uninstalled using:
# ./waf-light --prefix=/usr/ # ./waf-light uninstall
