/** @name djvuinfo
{\bf Synopsis}
\begin{verbatim}
djvudump <... iff_file_names ...>
\end{verbatim}
{\bf Description} --- File #"djvudump.cpp"# uses the facilities
provided by \Ref{IFFByteStream.h} to display an indented
representation of the chunk structure of an ``EA IFF 85'' file.
Each line represent contains a chunk ID followed by the chunk
size. Additional information about the chunk is provided when
program #djvuinfo.cpp# recognizes the chunk name and knows how to
summarize the chunk data. Furthermore, page identifiers are
printed between curly braces when #djvudump# recognizes a bundled
multipage document. Lines are indented in order to reflect the
hierarchical structure of the IFF files.
{\bf Example}
\begin{verbatim}
% djvuinfo graham1.djvu
graham1.djvu:
FORM:DJVU [32553]
INFO [5] 2325x3156, version 20, 300 dpi, gamma 2.2
ANTa [34] Page annotation
INCL [11] Indirection chunk (document.dir)
Sjbz [17692] JB2 data, no header
BG44 [2570] #1 - 74 slices - v1.2 (color) - 775x1052
FG44 [1035] #1 - 100 slices - v1.2 (color) - 194x263
BG44 [3048] #2 - 10 slices
BG44 [894] #3 - 4 slices
BG44 [7247] #4 - 9 slices
\end{verbatim}
