First install the above required external tools.
Then just unzip the sut-0.2.zip file and add the bin/ subdirectory to your system's PATH environment variable. Optionally do a logout/login of your user session to let the new system PATH environment variable really apply.
For Linux/Mac
For example you can extract the zip-files in /usr/local/ and add the following lines to your system wide bash configuration script /etc/profile:
export SUT_ROOT_PATH=/usr/local/sut-0.2
PATH=$SUT_ROOT_PATH/bin:$PATH; export PATH
Note: instead of a system install in /usr/local/ you could also do a personal install in your home directory. Then edit ~/.bashrc instead of /etc/profile.
For Windows
For example you can extract the zip-files in C:\Program Files and add the following to your system environment variables:
SUT_ROOT_PATH=C:\Program Files\sut-0.2
PATH=...;%SUT_ROOT_PATH%\bin
Note: instead of a system install in C:\Program Files you could also do a personal install in your home directory. Then add above variables to your user environment variables instead of the system environment variables.
