* Simple example that demonstrates how to read in and write out an
* Open Inventor model, essentially copying it. This process has no use
* per se, but can be used to sanity-check the import/export-related
* parts of Coin, and can be used as a starting point for utilities doing
* scene graph rewrites.

* Build the example using this command:
