/*
 * 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:
 *
 *   coin-config --build ivcp ivcp.cpp
