This software was suggested by Julien Delange and was realised by two EPITA students, Julio Guerra and Patrick Samy.
MSC is a graphical and textual language for the description and specification of the interactions between system components. The main area of application for Message Sequence Charts is as an overview specification of the communication behaviour of real-time systems, in particular telecommunication switching systems. Message Sequence Charts may be used for requirement specification, simulation and validation, test-case specification and documentation of real-time systems. MSCs are often used in combination with SDL, in particular the ITU specification and description language.

MSC Editor is simply composed of two layers: the back-end and the front-end. The front-end uses back-end's features. So the back-end is absolutely abstracted from any usage.
The back-end provides everything required to handle a MSC document: an abstract syntax tree (AST), a lexer, a parser and AST's visitors.
The parser takes an input and the standard it follows (MSC96 or
MSC2000) to generate the MSC's AST. The AST is represented in the
technical documentation (make doc) of msc::Ast class.
A DefaultVisitor provides the default traversal behavior of the
AST. Its first usage is the PrettyPrinter visitor thats prints an
AST without caring of how to traverse the AST, this is delegated to
the DefaultVisitor super class. So many other Visitors can be
imagined and they simply have to inherit from DefaultVisitor.
The front-end's first goal is to make the AST drawable by the target GUI. The decorator design pattern should be used for that purpose, making the drawable AST, a normal AST, i.e. compatible with every back-end feature.
Many front-ends can be implemented, using this same back-end.
This can be considered as the border between the back-end and the front-end. It simply defines graphical AST nodes for the target.
The GUI simply handles the graphical interface and user interactions.
