* MODULE : TeXmacs.h
* DESCRIPTION: Include file for communication of extern packages with TeXmacs
* COPYRIGHT : (C) 1999 Joris van der Hoeven

*******************************************************************************
* The TeXmacs communication protocol works as follows:
* - First of all, the protocol is dynamic. All protocols define
* the abstract structures 'TeXmacs_exports' and 'package_exports'.
* These structures contain the version of the protocol used
* and the versions of TeXmacs and the package
* - Version n of the concrete protocol implements two structures
* 'TeXmacs_exports_n' and 'package_exports_n'.
* The first structure contains all routines and data of TeXmacs,
* which may be necessary for the package.
* The structure 'package_exports' contains all routines and data
* of the package, which should be visible for TeXmacs
* - Now the package has to be a dynamically linkable library,
* which implements a function
* package_exports* get_my_package (int version);
* In order to link your package to TeXmacs, you will now have to
* call the TeXmacs function
* void package_declare (string name, string lib, string f, string init);
* Here 'name' is the name of your package under TeXmacs,
* 'lib' the name of the library, 'f' the function 'get_my_package' and
* 'init' an initialization string.
