Don't bother with this if you use debian, just install the .deb

Assumes the tarball is in your home dir :

As superuser (root) for system wide install (read the make file first!)

    cd ~/
    mkdir kewl
    cd kewl
    tar xzvf ../kewl.tgz
    make install

As a normal user:

    cd ~/
    mkdir .kewl
    cd .kewl
    tar xzvf ../kewl.tgz

You may also want to do this, logged in as whatever user you want to 
use kewl.

    If kewl has been installed by super user:

	echo exec kewl > ~/.xsession
	chmod u+x ~/.xsession

    If not:

        echo exec ~/.kewl/kewl > ~/.xsession
        chmod u+x ~/.xsession

Then log out of X, when you login again, "It Should Work"(tm).

Enjoy. :-)
