\description{
|
|
Use \code{singleton} to wrap contents (tag, text, HTML, or lists) that should
|
|
be included in the generated document only once, yet may appear in the
|
|
document-generating code more than once. Only the first appearance of the
|
|
content (in document order) will be used. Useful for custom components that
|
|
have JavaScript files or stylesheets.
