Skribe supports traditional ,(emph "references") (that is, references to some
part of documents) and ,(emph "hyperlinks") (that is visual marks enriching
texts that enable interactive browsing). Hyperlinks may point to
,(itemize (item [Inner parts of a document, such as a section or a figure.])
(item [Other documents, such as Web documents.])
(item [Other Skribe documents.])
(item [Specific part of other Skribe documents, such as a chapter
of another Skribe document.]))

,(itemize (item [,(emph "Refer to") marks. This is the role of the ,(tt "ref")
Skribe function.])
(item [,(emph "Set") marks. This is the role of the ,(tt "mark")
function. However, most Skribe functions that introduce text
structures (e.g., chapters, sections, figures, ...)
automatically introduce marks as well. So, it is
useless to ,(emph "explicitly") introduce a mark at the
beginning of these constructions in order to refer to them
with an hyperlink.]))]
