Actually, I can answer my own question is these steps:
1. Export the script file from an embedded database.
2. Open LibreOffice in which the Class Path contains the path to the hsqldb.jar file for version 2.50.
3. Connect to an empty database supplying the pertinent information.
4.Using Tools > SQL, Copy and paste the contents of the script file as described below. This external database now contains all of the tables, views, and data that the embedded database has. There are no queries, forms, nor reports.
5. Create a copy of the embedded database.
6. In the main database window of the external database, open the copy of the embedded database. Since the LibreOffice doing this is using HSQLDB 2.50, this action will remove all of the tables, views, and data from the embedded database. It however contains all of the queries, forms, and reports.
7. Since the external database and the embedded one are both using HSQLDB 2.50, clicking on an individual query, form, or report and drag and drop it from the main database window of one to the other.
The result is an external database with all of the tables, views, data, queries, forms, and reports that are part of the embedded database. There is a problem that has to be corrected in the forms: the form property for each form and subform. The Content property has to be modified to point to the correct the name of the table or query.
