When I had to use it, main problem was that it requires a subclass to implement
{{run()}}. I don't see how requiring {{run()}} is anyway related to what
ToolBase does. Requiring {{run()}} expects a certain structure to subclass.
All its interesting funcionality is implemented in {{static private}} members,

{{parseGeneralOptions()}} public. Then users won't be forced to subclass to get
its functionality.
