 initial support to read and write X3D files via the nist.gov 
 X3D translators. 
 Use at your own risk !

 It is wise to install SAXON (http://users.iclway.co.uk/mhkay/saxon/)
 as engine for a fast X3D to VRML translation.

 Warning: Currently the translators fail to produce valid VRML97 code for some
 rare used nodes like VisibilitySensor or Collision.
 Currently dune need valid code to work.

 To avoid dataloss, the temporary .wrl files are kept in temporay 
 directories like /tmp or c:\TEMP

 If you installed the x3dtranslators under Unix/Linux in the directories
 x3dv2 and v2x3d (according to the INSTALL documentation) and run 
 configure and recompile, you do not need to do anything.
 Otherwise you have to set the following environment variables (sh syntax)
 before you start dune:

 JAVA_PATH=/something_like/usr/java/bin/java
 export JAVA_PATH

 SAXON_FILE=saxon.jar
 export SAXON_FILE
 SAXON_PATH=/something_like/usr/local/src/x3d2vrml/saxon
 export SAXON_PATH

 X3DV2_FILE=x3dv2.jar
 export X3DV2_FILE
 X3DV2_PATH=/something_like/usr/local/src/x3dv2
 export X3DV2_PATH

 V2X3D_FILE=Vrml97ToX3dNist.jar
 export V2X3D_FILE 
 X3DV2_PATH=/something_like/usr/local/src/v2x3d
 export V2X3D_FILE

 If you use M$Windows, you also need to set the following environment
 variables (beside downloading and installing the files...) before you 
 run dune with something like:

 JAVA_PATH="C:\something_like\Program Files\JavaSoft\JRE\1.3\bin\java"
 SAXON_FILE=saxon.jar
 SAXON_PATH=D:\some_install_path\x3dv2
 V2X3D_FILE=Vrml97ToX3dNist.jar
 V2X3D_PATH=D:\some_install_path\v2x3d
 X3DV2_FILE=x3dv2.jar
 X3DV2_PATH=D:\some_install_path\x3dv2

 Under M$Windows NT4 you can set this enviroment variables via
 start -> settings -> system -> enviroment
