+\subsection{New \cs{showfloat} command}
+
+The package \pkg{fltrace} offers a (fairly low-level but very
+detailed) way to trace \LaTeX's float mechanism. This can help to
+understand why a certain float is placed into a certain region or why
+it shows up unexpectedly on a later page.  \LaTeX{} stores floats in
+registers named \cs{bx at A}, \cs{bx at B}, etc., and these names show up in
+the tracing information.
+%
+To display their contents you can now say
+\verb=\showfloat{=\textit{uc-letter}\verb=}= where \textit{uc-letter}
+is the uppercase letter (or letters) after \texttt{bx@} in the
+register name shown in the tracing. The command is generally
+available, whether or not you have loaded \pkg{fltrace}, because it is
+also useful when interpreting the tracing output of the
+\pkg{fewerfloatpages} package.
