/** @name djvm
{\bf Synopsis}\\
\begin{verbatim}
djvm [options] <djvu_doc_name> [djvufiles] [pagenum]
\end{verbatim}
{\bf Description} ---
File #"djvm.cpp"# and program #djvm# illustrate how class \Ref{DjVuDocEditor}
can be used to create and modify DjVu multipage documents. The program
demonstrates how to pack several DjVu single-page files together,
how to remove pages from a multipage document or how to insert new.
{\bf Arguments} ---
Depending on the task to be performed, the number and types of arguments
differ:
\begin{itemize}
\item To create a new document
#djvm -c[reate] <doc.djvu> <page_1.djvu> ... <page_n.djvu>#
This will package pages represented by files #<page_1.djvu>#
... #<page_n.djvu># into #BUNDLED# multipage DjVu document
#<doc.djvu># (see \Ref{DjVuDocument} for the explanation of
the #BUNDLED# format). The specified page files may include other
files (by means of #INCL# chunks). They will also be packed
into the document.
\item To insert a page
#djvm -i[nsert] <doc.djvu> <page.djvu> [<page_num>]#
This will insert page represented by file #<page.djvu># into
document #<doc.djvu># as page number #<page_num># (page
numbering starts from #1#). Negative or missing #<page_num>#
means to append the page.
The #<page.djvu># file can actually be another
multipage DjVu document. In this cases, all pages from that
document will be inserted into #<doc.djvu># starting from
page #<page_num>#.
\item To delete a page
#djvm -d[elete] <doc.djvu> <page_num>#
This will remove page number #<page_num># from document
#<doc.djvu>#. If there is only one page left in #<doc.djvu>#
after deletion, it will automatically be converted to a
single page DjVu file format. Page numbering starts from #1#.
\item To view document contents
#djvm -l[ist] <doc.djvu>#
This will list all files composing the given document #<doc.djvu>#.
The files list includes the names of page files plus names
of any files included into the page files by means of
#INCL# chunk.
\end{itemize}
