New Features
============
+ * Modified VFL file driver 'flush' function to accept an extra parameter,
+ which indicates that the file will be immediately closed. This may allow
+ VFL drivers to bypass syncronizations that are also performed when the
+ file is closed. Specifically, the MPI-I/O VFL driver bypasses the
+ MPI_File_sync() call, since MPI_File_close performs file syncronization
+ also. QAK - 2002/05/10
* Allow the metadata writes to be shared among all processes, easing the
- burden on process 0.

* New functions H5Glink2 and H5Gmove2 were added to allow link and move to
be in different locations in the same file. The old functions H5Glink
and H5Gmove remain valid. SLU - 2002/04/26
