In computing science, the term designates a particular type of script code. The programming languages used to write these programs are called scripting languages, and are used to write instructions to be included in web pages, which are to be interpreted by the browser. Typical operations performed by shell scripts include file manipulation, program execution, and text printing.

We write here only of the scripts that served here for this site relating them to the various pages to show how they work. Elementary scripts are written directly and can be copied and pasted elsewhere, while those coming with compressed the links for downoad are available.

Now we make an example of scripts used to have succession of images with fading effects.
