| Merges input notice files to the output file while ignoring duplicated files |
| This script shouldn't be confused with build/soong/scripts/generate-notice-files.py |

| installed. This script has rather limited scope; it is meant to create a merged |
| notice file for a set of modules that are packaged together, e.g. in an APEX. |
| The merged notice file does not reveal the individual files in the package. |
