But you need to know the exact file name (dot or dot.exe), and
env.PATH is not always portable because of case on Windows, where it
can be Path, path, or PATH or else. Your <exec> approach is more
reliable, but more verbose. Maybe a <redirector> in exec would help,
and a "grep" of know output from the command to see if it works or
not. Just suggestions to explore. --DD
