This is a helper process that can take a list of items and pass information about the list into another process. For example, with a list of filenames with their path, the first item in the list, the last item in the list, or a count of the items in the list can be passed to another process.
Example:
1. Use the Copy tool to copy a file and pass the output to Describe List.
2. Pass the First file (the only file in this case) from the Describe List tool to the update port of the Add Features tool.
This way, Add Features can update a copy of a file and avoid overwriting the original file.
