Create log is the simplest way to create a text file directly stored as a dataset*.
These are some of the use cases we've created this app for:
Generating a XML dataset on the fly that will follow the job trough the flow;
Genarating a JSON with variable for a web API;
Log info in a markdown file (.md).
*Note that this app will check the format and syntax of the output file only for XML, JDF or XMP dataset.
We use it all the time and is more useful than the name says. Can't live without it.
