Command-line CDF Checkers

The SKTEditor GUI application contains two separate CDF standard checking functions.  The first checks a CDF for compliance with the ISTP/SPDF guidelines.  The second checks a CDF for compliance with project-specific guidelines (e.g., MMS Mission CDF File Format and Units of Measure Guides).  This CDF checking software can also be run from a CLI (in addition to running it from within SKTEditor).  An advantage to running the software from a CLI is to automate the checking of many files.   Follow these instructions for installing and running the checkers from a CLI.


This application may be uninstalled by following the Uninstall Instructions.
