+# Builds necessary JARs, generates data and queries, and runs fuzz tests for Comet Spark.
+# Environment variables:
+#   SPARK_HOME - path to Spark installation
+#   SPARK_MASTER - Spark master URL (default: local[*])
+#   SCALA_MAJOR_VERSION - Scala major version to use (default: 2.12)
+#   SPARK_MAJOR_VERSION - Spark major version to use (default: 3.5)
+#   NUM_FILES - number of data files to generate (default: 2)
+#   NUM_ROWS - number of rows per file (default: 200)
+#   NUM_QUERIES - number of queries to generate (default: 500)
