The package offers LaTeX macros for typesetting critical editions of poetry.
Its features include automatic linenumbering, generation of separate endnotes
sections for emendations, textual collations, and explanatory notes, special
marking for cases in which page breaks occur during stanza breaks, running
headers of the form 'Notes to pp. xx-yy' for the notes sections, index of
titles and first lines, and automatic generation of a table of contents.
