With this option, a configuration (set of options) given on the command line may
be saved in a named configuration or in the default configuration when
<ConfigName> is omitted. When the configuration already exists the option
[@o]--replace-config must be used else the option [@o]--save-config is sufficient.

The default configuration is saved in <StudyRoot>/MetaData/simtree.conf. A named
configuration is saved in <StudyRoot>/MetaData/simtree-<ConfigName>.conf.
