Select tasks to include by

• Task type: --task-type. Valid values are reload and ext-program.
• Task tag: --task-tag. Get ids of all tasks with the specified tags, then get root tasks and include all their task chains in the graph.
• Task id: --task-id. Get root tasks and include all their task chains in the graph.
• App id: --app-id. Get associated task ids, then get root tasks and include all their task chains in the graph.
• App tag: --app-tag: Get associated task ids, then get root tasks and include all their task chains in the graph.

If an option is specified on the command line, Ctrl-Q should verify that the specified id/tag exists in QSEoW, and warn if not.
