Files #"Template.h"# and #"Template.cpp"# are not used for anything but
the current programming and documentation standards in the DjVu reference
library. This doc++ comment briefly describes the abstractions defined in
this files.  It must mention all the files involved in implementing this
features, as well as references to the main classes \Ref{classname}.

This comment may contain additional sections as follows:

{\bf Algorithmic Remarks} --- Comments about the algorithms, their
performance and their limitations.

{\bf Historical Remarks} --- Comments about the successive revisions of
this file and other anecdotical details. This is where we can amuse the
reader with funny details.

{\bf ToDo} --- Things that we have been thinking to do but did not
fully implement yet. It should explain how we plan to modify the current
code could be modified to implement these things. People who change this
code thus should avoid jeopardizing these plans.

{\bf Example} --- It would be cool to demonstrate how these functions
can be used by providing a small segment of C/C++ code.
\begin{verbatim}
ExampleClass toto(3,4);
toto.draw(mywin);
\end{verbatim}

This main doc++ comment is followed by a few doc++ entries.
\begin{itemize}
\item the "memo" field contains a single line description of the file.
\item the "version" field contains a cvs magic expression.
\item the author fields contains a list of authors and email addresses.
(the #\\# termination breaks the line.)

//T// The magic doc++ comment above opens a doc++ context.

//T// Now comes the 'interface part' of the file.
//T// The c++ classes and public functions are defined there.
//T// Doc++ comments must be inserted for all functions
//T// intended to be used by other people.
//T//
//T// Quite often c++ sucks and it is necessary to have public or external symbols
//T// that actually are only there for implementation purposes.
//T// It is good to give a comment but this should not be a doc++ comment
//T// (see class GPool in GContainer.h).  All other 'public' and 'protected'
//T// members should have a doc++ comment. There is no need to comment 'private'
//T// members, although a regular comment can be useful (not a doc++ comment).

/** One-line class description.
Long description. There is no need to repeat the class name in the
one-line description. The long description should describe the abstraction
and point the user to the main member functions.  An example could be
inserted when this is informative and not redundant with the file
description.  Templates should document which member functions are
required for their type argument. The availability of non availabilty of a
copy constructor/copy operator can be specified when appropriate.
See the doc++ documentation for available LaTeX constructs.
