 First, generate a directory with a set of examples in `.sql` files. For example, to create the examples in the directory `./examples`, invoke:

-    java -jar translate-ng-7.1.6.jar -examples ./examples/
+    java -jar translate-ng-7.1.8.jar -examples ./examples/

 Now, you may edit the existing or add new examples in the directory. After you're done, translate them into relational algebra:

-    java -jar translate-ng-7.1.6.jar -dir ./examples/
+    java -jar translate-ng-7.1.8.jar -dir ./examples/

 The results will be stored in `./examples/.txt` and `.xlsx` files. The generated `.txt` files include the generated spreadsheet formulas. The first couple columns are filled with `=NA()` and represent columns, where the user will enter her data.

 The different spreadsheet columns in the generated file have different meaning. The leftmost columns represent the tables declared with the CREATE TABLE statements. This is where the user inputs data. The next couple couple columns, hidden by default, are intermediate results of computing the query results. And finally, the columns that are on the right of the user input data but are not hidden represent the resultant relations of the queries chosen by the user.

+The generated spreadsheet document has only two rows filled in. They are presented in the spreadsheet program with a "N/A!" text in gray. Those are workspace rows, where the user inputs data. To input more than two rows, the user must extend the workspace area. To do so, the user must select the second row (and only the second row, with care not to select the first row) and autofill it down. This can be done with key bindings by selecting an area spanning the second row and subsequent rows that are to be autofilled and executing the autofill with the Ctrl-D key binding.

 ###Examples

 This is an incomplete list of sql queries and equivalent relational algebra formulas. It references the database schema defined above.
