man.endnotes.are.numbered — Number endnotes?
a number (in square brackets) is displayed inline after the rendered inline contents (if any) of the notesource
the contents of the notesource are included in a numbered list of endnotes that is generated at the end of each man page; the number for each endnote corresponds to the inline number for the notesource with which it is associated
The default heading for the list of endnotes is
NOTES. To output a different heading, set a value
The endnotes list is also displayed (but without
numbers) if the value of
If the value of
zero, numbering of endnotess is suppressed; only inline
contents (if any) of the notesource are displayed inline.
If you are thinking about disabling endnote numbering by setting
the value of
man.endnotes.are.numbered to zero,
before you do so, first take some time to carefully
consider the information needs and experiences of your users. The
square-bracketed numbers displayed inline after notesources may seem
obstrusive and aesthetically unpleasing,
but in a text-only output format, the
numbered-notesources/endnotes-listing mechanism is the only
practical way to handle this kind of content.
Also, users of “text based” browsers such as
lynx will already be accustomed to seeing inline
numbers for links. And various "man to html" applications, such as
the widely used man2html (
application, can automatically turn URLs into "real" HTML hyperlinks
in output. So leaving
at its default (non-zero) value ensures that no information is
lost in your man-page output. It just gets
The handling of empty links is not affected by this parameter. Empty links are handled simply by displaying their URLs inline. Empty links are never auto-numbered.
If you disable endnotes numbering, you should probably also set
man.font.links to an empty value (to
disable font formatting for links.
 A “non-empty” notesource is one that looks like this:

 As far as notesources that are links, ytou might
think it would be better to just display URLs for non-empty
links inline, after their content, rather than displaying
square-bracketed numbers all over the place. But it's not better. In
fact, it's not even practical, because many (most) URLs for links
are too long to be displayed inline. They end up overflowing the
right margin. You can set a non-zero value for
man.break.after.slash parameter to deal with
that, but it could be argued that what you end up with is at least
as ugly, and definitely more obstrusive, then having short
square-bracketed numbers displayed inline.
