main window has the project frame that appears in its upper-left part.
By default it is empty. It is not empty if some project has been either
opened or newly created.
The frame contains the project name, the input
catalog name, and a brief description of the sequence of tasks considered.
If additional catalogs exist in a task, then the list of these
add-ins is provided as branches of the project tree (for details see
8.1 Manage Project). Compilation Catalog Program
