LicStr='SPDX-License-Identifier: \(Apache-2.0 OR MIT\)'

# Remove these files from the list of all files without 'SPDX'

egrep -LR "$LicStr" . | egrep -v '[.](o|a|filters|pdf|svg|gif)$' |

  egrep -v '[.]/src/examples/docs' |
  egrep -v '[.]/src/test/TEST_.*'    > check-license.files

# Add these file back to the list

egrep -LR "$LicStr" ./src/test/TEST_* |

egrep -LR "$LicStr" ./src/test/TEST_* |
