+ * This program takes an IDF base name, loads the board outline
+ * and component outine files, and creates a single VRML file.
+ * The VRML file can be used to visually verify the IDF files
+ * before sending them to a mechanical designer. The output scale
+ * is 10:1; this scale was chosen because VRML was originally
+ * intended to describe large virtual worlds and rounding errors
+ * would be more likely if we used a 1:1 scale.
