These scripts are made to each do one thing well and be combined with each other. Many are linked to a keybinding in my X session.
Feel free to copy them all or in part, read them, study them, take them apart, copy-paste lines from them and publicly ridicule them as you like.
Send any suggestion for improvement at sebastiano@tronto.net.
I might add some examples here at some point, for now just look at the source code.
