{bigfoot} is a package that provides an all-encompassing interface to {footnotes}.
The bigfoot package is intended for texts with several layers of footnotes (apparata), as used in critical editions. It has many options; unfortunately, most "expert" options are not well documented. The package excerpt on CTAN states:
The package aims to provide a ‘one-stop’ solution to requirements for footnotes. It offers:
- Multiple footnote apparatus superior to that of the
manyfoot;- Footnotes can be formatted in separate paragraphs, or be run into a single paragraph (this choice may be selected per footnote series);
- Things you might have expected (like
\verb-like material in footnotes, and colour selections over page breaks) now work.
