3.2.7 Table of Contents
-----------------------

A package may handle a table of contents by directing section heading
macros to save section heading text and the page number where it occurs
for use in a later entry for a table of contents.  It writes the
collected entries at the end of the document, once all are known, upon
request.  A row of dots (a leader) bridges the text on the left with its
location on the right.  Other collections might work in this manner,
providing lists of figures or tables.

   A table of contents is often found at the end of a GNU 'troff'
document because the formatter processes the document in a single pass.
The 'gropdf' output driver supports a PDF feature that relocates pages
at the time the document is rendered; see the 'gropdf(1)' man page.
Type 'man gropdf' at the command line to view it.
