# ----------------------------------------------------
# This script uses the Open Source asn1c to check all used ASN.1 modules
# are compile clean (no guarantee the generated code is valid).
#
# The used compile binary was built from here:
#   https://github.com/brchiu/asn1c/commits/velichkov_s1ap_plus_option_group_plus_adding_trailing_ull
#
# The referenced ISO ASN.1 modules are pulled from the ISO Standards Maintenance Portal
# Yet not all are compile clean, thus minor fixed need to be done.
# All these changes are irrelevant for the resulting encoding.
#  - Fixing duplicate DE tags
#  - Fixing OID typo
#  - Removing unused types (which bloat the IMPORTS)
# ----------------------------------------------------
