+## ------ ##
+## Usage. ##
+## ------ ##
+
+# This file is a library for parsing options in your shell scripts along
+# with assorted other useful supporting features that you can make use
+# of too.
+#
+# For the simplest scripts you might need only:
+#
+#   #!/bin/sh
+#   . relative/path/to/funclib.sh
+#   . relative/path/to/options-parser
+#   scriptversion=1.0
+#   func_options ${1+"$@"}
+#   eval set dummy "$func_options_result"; shift
+#   ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# warranty; '.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.
+
+## -------------- ##
+## Configuration. ##
+## -------------- ##
+
+# You should override these variables in your script after sourcing this
+# file so that they reflect the customisations you have added to the
+# option parser.
+
+# The usage line for option parsing errors and the start of '-h' and
+# '--help' output messages. You can embed shell variables for delayed
+# expansion at the time the message is displayed, but you will need to
+# quote other shell meta-characters carefully to prevent them being
+# expanded when the contents are evaled.
+usage='$progpath [OPTION]...'
+
+# Short help message in response to '-h' and '--help'.  Add to this or
+# override it after sourcing this library to reflect the full set of
+# options your script accepts.

+    - Collective Metadata I/O
+    
+    Calls for HDF5 metadata can result in many small reads and writes. On metadata 
+    reads, collective metadata I/O can improve performance by allowing the library
+    to perform optimizations when reading the metadata, by having one rank read the 
+    data and broadcasting it to all other ranks.
+
+    Collective metadata I/O improves metadata write performance through the 
+    construction of an MPI derived datatype that is then written collectively 
+    in a single call. For more information see

+Issues Addressed in this Release 
+================================
+    - h5format_convert tool didn't downgrade version of the superblock. Fixed. See
+      Known Problems section.  EIP 2016-01-11.
 
+    - It was reported that alpha0 crashed when used with multiple threads. 
+      The issue exists in the HDF5 library versions 1.8 and 1.9. 
+      The problem is related to a shared file pointer used in the misc. data 
+      structures. The thread-safe library exposed paths in the library where 
+      file pointer becomes invalid. Alpha1 release contains the fixes for the specific 
+      use case as decribed in HDFFV-9643.
+      We will keep working on identifying other paths in the library with similar problem
+      and fixing the issue.  EIP 2016-01-15
