* For example, if you are generating scripts to allow
* user to automatically create a database, then
* you might want the <code>$databaseName</code>
* to be placed
* in the initial context so that it is available
* in a script that might look something like the

* <code><pre>
* #!bin/sh
*
* echo y | mysqladmin create $databaseName
* </pre></code>
* The value of <code>$databaseName</code> isn't critical to
* output, and you obviously don't want to change
* the ant task to simply take a database name.
* So initial context values can be set with
