Configuration tags

| << | >> |

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 .
