This component is an attempt to provide an portable replacement for the Perl
DBI module as used by the Deployment scripts.

The file DBI.pm must be placed in PERL's INC path before the built-in modules.
The jar files MUST be placed in the same directory.

This version accepts SELECT requests on its STDIN and streams results out
STDOUT. It appears to be several orders of magnitude faster than the previous
effort for multiple queries as the connection is only established once.
