20 # This shell script is used to create a descriptor package
21 # The main functions of this script include:
22 # - Generate checksums.txt file
23 # - Generate a tar.gz file
24 # This script can be used to create the required folders for
25 # a descriptor package and a template descriptor
27 # Usage: generate_descriptor_pkg.sh <base-directory> <package-directory>
29 # Descriptor names should be
30 # - (nsd|vnfd).(yaml|yml|json|xml)
31 # - *_(nsd|vnfd).(yaml|yml|json|xml)
32 # - *_(nsd|vnfd)_*.(yaml|yml|json|xml)
