Differences between TIBCO Enterprise Runtime for R and Open-source R
In TIBCO Enterprise Runtime for R, 'uid', 'gid', 'uname' and 'grname' fields are never included.
The 'exe' field is provided on all platforms, but says only "no" or "yes". In open-source R on Windows,
it says "no", "win64", or "win32".
