Footnote Commands
-----------------

  In Texinfo, footnotes are created with the `@footnote' command.  This
command is followed immediately by a left brace, then by the text of
the footnote, and then by a terminating right brace.  Footnotes may be
of any length (they will be broken across pages if necessary), but are
usually short.  The template is:

     ordinary text@footnote{TEXT OF FOOTNOTE}

  As shown here, the `@footnote' command should come right after the
text being footnoted, with no intervening space; otherwise, the footnote
marker might end up starting a line.

  For example, this clause is followed by a sample footnote(1) (Note:
Footnote Commands-Footnote-1); in the Texinfo source, it looks like
this:

     ...a sample footnote@footnote{Here is the sample
     footnote.}; in the Texinfo source...

  As you can see, the source includes two punctuation marks next to each
other; in this case, `.};' is the sequence.  This is normal (the first
ends the footnote and the second belongs to the sentence being
footnoted), so don't worry that it looks odd.

  In a printed manual or book, the reference mark for a footnote is a
small, superscripted number; the text of the footnote appears at the
bottom of the page, below a horizontal line.

  In Info, the reference mark for a footnote is a pair of parentheses
with the footnote number between them, like this: `(1)'.  The reference
mark is followed by a cross-reference link to the footnote's text.

  In the HTML output, footnote references are marked with a small,
superscripted number which is rendered as a hypertext link to the
footnote text.

  By the way, footnotes in the argument of an `@item' command for a
`@table' must be on the same line as the `@item' (as usual).  Note:
Two-column Tables.
