The name of the script. This appears in the script manager and monkey menu, and is also used to determine whether to overwrite an old version of a script or to install it separately. If no name is provided, it will be inferred from the file name.
The namespace, along with the name, is used to determine whether to overwrite an old version of a script or to install it separately. A script author will usually put all of their scripts under one common namespace, and then assign each script a unique name. If two scripts have the same name, but a different namespace, they can co-exist. However, two scripts of the same name in the same namespace are assumed to be replacements for one another. While the namespace is non-semantic, it should be a URI. If no namespace is provided, it is assumed to be the domain from which the script is installed. Since a script can live on various servers or on a local file system, authors should specify this.
