What is the purpose of the metadata at the beginning of a script?

[algorev]

So at the beginning of every red script there is that Red [] section where some metadata is, such as the title of the script. I'm just wondering: what is the purpose of that section? What use cases do the Red developers see for integrated script metadata? If I put a title to my script, by what tools might it be used?

Hi. A few examples:

• http://www.rebol.org/st-topic-details.r?tag=level//beginner you can see how an external library can extract info from standard header fields
• title and icon are used to change program's info and appearance in Windows Explorer
• CLI library uses various items, such as title, author, license, rights and version to generate text for --version and --help arguments
• other reducers when reading the code can reason about what it does, how to use it, who wrote it, who to contact, how to license, etc.
• needs field will be used by module system once we have it (currently it understands only View & Audio modules)
• imagination is the only limit :)
