+// EPER Jetstream Database is a low complexity data and code storage solution. It is a hardened file system that you can review, verify, and certify cheaper.
+// We do not allow it to grow more than 1000 lines of code. This allows users to customize with AI tools.
+// No branding. It just works mostly for distributed in memory storage like Redis, Memcached or SAP Hana.
