from the comments of the new file
This software provides EMACS org-babel export support for message
sequence charts. The mscgen utility is used for processing the
sequence definition, and must therefore be installed in the system.
Mscgen is available and documented at
http://www.mcternan.me.uk/mscgen/index.html
This code is directly inspired by Eric Schulte's ob-dot.el
Example:
msc {
A,B;
A -> B [ label = "send message" ];
A <- B [ label = "get answer" ];
}
Header for alternative file type:
This differs from most standard languages in that
1) there is no such thing as a "session" in mscgen
2) we are generally only going to return results of type "file"
3) we are adding the "file" and "filetype" header arguments
4) there are no variables
