            <h3>SYNOPSIS</h3>
            <div>KVS is the light version of client interface on top of BTREE database
                 abstractions strive to support the basic features: </div>
            <div>
                 <ul>
                 <li>Polymorphic tuples aka extensible records;</li>
                 <li>Basic schema for chain storage;</li>
                 <li>Backends: MNESIA, FS, ROCKS;</li>
                 <li>Extremely compact and battle-tested: 500 LOC.</li>
                 </ul>
            </div>
            <div>This is an essence and fruit of KVS; the abstract term interface
                 with naive yet productive stream implementation. Useful for simple
                 blockchains, messaging, storage, processing systems, and banking industry.
                 KVS is used in BPE and BANK applications.</div>
