This template takes three arguments, Book, Chapter, and Line, as follows:
{{Xenhell|Book|Chapter|Line}}. Book and Chapter identify a chapter in Xenophon, and line is a line number or range of line numbers within that chapter. The template produces a link to that chapter of Xenophon on the Perseus Digital Library mirror at the university of Chicago, with the link text being Book.Chapter.Line. The template is intended for use in citations, and should generally be substed.
Thus, {{Xenhell|1|6|2-8}} produces 1.6.2-8.
