+This module provides Python dataclass models for representing a package list
+in a format compatible with the OSS Review Toolkit (ORT)
+`CreateAnalyzerResultFromPackageListCommand`.
+
+The models are simplified adaptations of the Kotlin classes from:
+https://github.com/oss-review-toolkit/ort/blob/main/cli-helper/src/main/kotlin/commands/CreateAnalyzerResultFromPackageListCommand.kt
+
+This module is intended for generating ORT-compatible YAML package lists from Python
