\Ref{DjVmDir0} class responsible for reading and writing the directory

of a multipage all-in-one-file DjVu document (usually referred to as

{\bf DjVm} document.

This is {\bf not} a navigation directory, which lists all the pages

in a multipage document. The navigation directory is supported by class

/** Directory of all-in-one-file DjVu documents (also known as DjVm documents).
|
|
This class can read and write the directory (table of contents, in other
|
|
words) of a DjVm document. This table of contents lists all {\bf files}
|
|
included into the document, not {\bf pages} like \Ref{DjVuNavDir} does.
|
|
It is normally stored in the document inside {\bf DIR0} chunk where
|
|
{\bf "0"} refers to the version number.
|
|
|
|
An object of this class can be created either as a result of the decoding
|
|
of an existing DjVm file, or manually by calling the default constructor
|
|
and adding later directory entries by means of \Ref{add_file}() function.
|
|
|
|
You normally will not want to create or decode this directory manually.
|
|
\Ref{DjVmFile} class will do it for you. */
