Event::ExecFlow offers a high level API to declare jobs, which mainly execute external commands, parse their output to get progress or other status information, triggers actions when the command has been finished etc. Such jobs can be chained together in a recursive fashion to fulfill rather complex tasks which consist of many jobs.
Additionally it defines an extensible API for communication with the frontend application, which may be a written using Gtk2, Tk or Qt or is a simple text console program.
In case of Gtk2 a custom widget for displaying an Event::ExecFlow job plan, including progress updates, is shipped with the Gtk2::Ex::FormFactory package.
