Thank you for adding pipe_tasks as an optional dependency. Now that I see it I am a bit uneasy about the duplication between the ReadMe file and the ups table file. I naively expected that you would add pipe_tasks to the table file but not the ReadMe. Yet the ReadMe has always had redundancies, since it asks the user to setup the desired obs_ package and validation_data_ package. Furthermore, it makes a great training tool for how to run processCcd.py and other tasks. So asking the user to explicitly set up the pipe_tasks in addition to the correct obs_ package and, in this case, validation_data_ package is clearly a good idea. So I like the new ReadMe.
However, I'm nervous about the existing and new redundancy between the ReadMe and the eups table file. I lean towards removing obs_ and validation_data_ from the ups table file. I am more ambivalent about leaving pipe_tasks in there, but with the helpful update of the ReadMe file I suspect even that should go.
Use your best judgement and thank you for your work on this valuable tool.
