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
