Of course this assumes the current directory is the one containing the my.data
file. By default it won't be, because the tool inherits the current directory
from the app, and IIRC when an app is launched the CWD is set to the root
directory of its bundle.
In general it's not a good idea to depend on the CWD in an app anyway. Why not
pass the absolute path of the data file as a command-line argument to the tool
from NSTask?

Um, yeah. But you haven't said why you commented it out. From what I remember
about NSTask, that line would have set things up so your existing tool would
work.
