OpenGrADS Bundle v2.0.a5.oga.1 available

All,

  I have refresh the sources and binaries for the OpenGrADS Bundle on
sourceforge:

https://sourceforge.net/project/showfiles.php?group_id=161773&package_id=305032&release_id=662661

  The main changes are:

1) A bug has been fixed in the UDX interface which was causing "exec
script" to fail. This is an important one, please update.

2) I have revised the internals of the Bundle implementation so that
it should work now with USB flash drives.

 As of this writing, most binaries have been updated except for
FreeBSD 7 (FreeBSD 6.3 has been updated). Make sure the files you
download start with "grads-2.0.a5.oga.2" (notice the "2" at the end.)

 Let me know of any problems.

 Enjoy,

    Arlindo
