>/**
> * Copied from ant's 1.6.5 SQLExec.java
> * Executes a series of SQL statements on a database using JDBC.
> *
> * <p>Statements can
> * either be read in from a text file using the <i>src</i> attribute or from
> * between the enclosing SQL tags.</p>
> *
> * <p>Multiple statements can be provided, separated by semicolons (or the
> * defined <i>delimiter</i>). Individual lines within the statements can be
> * commented using either --, // or REM at the start of the line.</p>
> *
> * <p>The <i>autocommit</i> attribute specifies whether auto-commit
should be
> * turned on or off whilst executing the statements. If auto-commit is turned
> * on each statement will be executed and committed. If it is turned off the
> * statements will all be executed as one transaction.</p>
> *
> * <p>The <i>onerror</i> attribute specifies how to proceed when an
error occurs
> * during the execution of one of the statements.
> * The possible values are: <b>continue</b> execution, only show the error;
> * <b>stop</b> execution and commit transaction;
> * and <b>abort</b> execution and transaction and fail task.</p>
