/**
* A command-line JDBC SQL tool supporting both interactive and
* non-interactive usage.
*
* See JavaDocs for the main method for syntax of how to run from the
* command-line.
*
* Programmatic users will usually want to use the objectMain(String[]) method
* if they want arguments and behavior exactly like command-line SqlTool.
* But in many cases, you will have better control and efficiency by using
* the SqlFile class directly. The file
* src/org/hsqldb/sample/SqlFileEmbedder.java
* in the HSQLDB distribution provides an example for this latter strategy.
*
