ERTLab employs keywords (tags) to indicate configuration
information. Each keyword starts with the # symbol. The
comment character is !. Any information placed between ! and the end of a
file line is ignored. Blank lines are also ignored.
The configuration tags can be present both in the schedule-data and in the
configuration files.
The complete list of possible commands is documented in the
example below. Descriptions of the configuration
parameters corresponding to the tags and how they affect the models are
found in the Configuration Command Reference
