- similar to -dry-run handling, can be interrogated from argList,
which makes it simpler to add into utilities.
- support multiple uses of -dry-run and -verbose to increase the
level. For example, could have
someApplication -verbose -verbose
and inside of the application:
if (args.verbose() > 2) ...
BUG: error with empty distributed roots specification (fixes #2196)
- previously used the size of distributed roots to transmit if the
case was running in distributed mode, but this behaves rather poorly
with bad input. Specifically, the following questionable setup:
distributed true;
roots ( /*none*/ );
Now transmit the ParRunControl distributed() value instead,
and also emit a gentle warning for the user:
WARNING: running distributed but did not specify roots!
