First release of defrag.pl

Defrag script "defrag.pl" now included. This is the first release of this program, so caution is advised. In this version, partitioned tables are defraged only if all partitions/subpartitions reside in the named tablespace. The next release will support partition exchanges and resizing of all partitions within in named tablespace. Also included in the distribution is a README file. Please do. It contains instructions for reporting bugs and highlights the Open Discussion forum available here at SourceForge. Please let me know about your successes and failures -- together we can make this a very useful tool.
