 \rule[@var{raise}]@{@var{width}@}@{@var{thickness}@}
 @end example
 
-The @code{\rule} command produces @dfn{rules}, that is, lines or
-rectangles.  The arguments are:
+Produce a @dfn{rule}, a rectangle.
 
- at table @var
- at item raise
-How high to raise the rule (optional).
+ at cindex Halmos symbol
+ at cindex tombstone
+This produces a rectangular blob of ink, sometimes called a Halmos
+symbol, often used to mark the end of a proof.
 
- at item width
-The length of the rule (mandatory).
+ at example
+\newcommand@{\qedsymbol@}@{\rule@{0.4em@}@{2ex@}@}
+ at end example
 
- at item thickness
-The thickness of the rule (mandatory).
- at end table
+ at PkgIndex{amsthm}
+ at noindent
+The @file{amsthm} package includes this command, with a somewhat
+different-looking symbol.
 
+The mandatory arguments @var{width} and @var{thickness} are rigid
+lengths (@pxref{Lengths}).  The optional argument @var{raise} is also a
+rigid length, and tells @LaTeX{} how much to raise the rule above the
+baseline, or lower it if the length is negative.
 
+This produces a line, a rectangle that is wide but not tall.
+
+ at example
+\noindent\rule@{\textwidth@}@{0.4pt@}
+ at end example
+
+ at noindent
+The line is the width of the page and 0.4 at tie{}points tall.  This line
+thickness is common in @LaTeX{}.
+
+A rule that has zero width, or zero thickness, will not show up in the
+output, but can cause @LaTeX{} to change the output around it.
