+# A Package that complies with the Best Practice for Earth Observation Application Package needs to:
+#
+# * Be a valid CWL document with a single Workflow Class and at least one CommandLineTool Class
+# * Define the command-line and respective arguments and container for each CommandLineTool
+# * Define the Application parameters
+# * Define the Application Design Pattern
+# * Define the requirements for runtime environment
+#
+# The Workflow class steps field orchestrates the execution of the application command line and retrieves all the outputs of the processing steps.
