 Script to scan the input directory for files with name "olive_ci.json"
 and generate output that can be set as strategy matrix for github job.
 
+When --changed-files is provided (one file path per line), only recipes
+whose directory contains at least one changed file are included.
+This avoids running all recipes when a PR only touches one recipe folder.
+
 Example:
     python generate_matrix.py <input directory> <ubuntu|windows> <cpu|cuda>
+    python generate_matrix.py <input directory> <ubuntu|windows> <cpu|cuda> --changed-files changed.txt
