# Produce a commercial-license-override sample alongside the pinned GPL samples.
#
# This script is illustrative: it derives wolfssl-<ver>.commercial.{cdx,spdx}.json
# from the GPL pinned files by swapping the license fields and adding a
# wolfssl:license:override property. Auditors see the same build configuration,
# the same hashes of the source list, and a different license declaration —
# exactly the diff a paying wolfSSL customer's SBOM should show.
#
# In production, regenerate via:
#   CRA_LICENSE_OVERRIDE=LicenseRef-wolfSSL-Commercial \
#       ./scripts/generate-wolfssl-sbom.sh
