It's warning about the usage of dash-separated names like 'script-dir' and 'install-scripts,' which will not be supported in future versions. Instead, underscore names like 'script_dir' and 'install_scripts' should be used. Additionally, it suggests that the 'easy_install' command is deprecated and recommends using 'build' and 'pip' for installation.
