+load_products_in_mongodb.pl --product_ids_file file_name
+
+load_products_in_mongodb.pl is a script that loads products from a file containing a list of product ids (one per line) into MongoDB.
+
+It is also possible to use _ids in JSON format from mongoexport:
+{"_id":"3564700611494"}
+
+e.g. mongoexport --host 10.1.0.102 --db=off --collection=products --query='{"\$expr": {"\$ne":["\$_id","\$id"]},"data_sources_tags":"producers"}' --fields=_id > off-pro-products-on-off.json
+(remove the \ in \$)
+
+The script goes through the list of product ids, retrieves the corresponding products from the file system, and loads them into MongoDB in the right database and collection.
