Specifying Export Criteria
When exporting a package you can specify export criteria using command line tools. Additionally, you can also use recipe files to export a package. The recipe file instructions execute at the command line.
Command line—The command line utility allows for the full or abbreviated execution of Creo Packages commands and arguments.
