29 <p>If you make modifications to Blitz and wish to keep them proprietary, you become subject in full to the Sleepycat <a href="http://www.sleepycat.com/download/licensinginfo.shtml">licensing conditions</a>. Under some very limited circumstances, Sleepycat permits usage of Blitz/Db without requiring a commercial license but in the majority of such cases, you will be required to pay for a commercial Db license.</p> |
