I would request that by this first DL each contributor would

(1) debug tools they have developed,
(2) that the tools can be opened using zef_tool_start.m function,
(3) check that those can be run both in graphical user interface mode and on command line in terminal (without the java interface or any graphics available), and
(4) The scripts folder includes a self-supported demonstrator that (a) starts the interface, (b) imports or opens a project, (c) runs the tool with test data (numerical simulations if available, a small set can be uploaded in the repository, if needed and if it is ok to do so regaring any IPRs, alternatively an online dataset can be downloaded for the deployment run, if it is not applicable otherwise).
