Merge pull request #338 in HDFFV/hdf5 from ~LRKNOX/hdf5_lrk:develop to develop

* commit '98567db19290dc07cc86efae720b0dc457ae9f65':
  output_filter.sh:         Comment added to address HDFFV-8270.  The sample ontput in the         file's comments are not up-to-date with the scripts in the file         that remove output unique to certain systems when running test         scripts.  This output doesn't match expected output files for         the tests, causing them to fail.  Ther output_filter.sh file         removes such output.  Currently we don't have access to these         systems to update the comments.

+# Comment added to address HDFFV-8270:
+# As I understand it, the purpose of this file is to remove extraneous messages 
+# that appear in stdout and stderr on some machines that have been tested outside 
+# of the HDF Group realm.  The purpose of this script is to filter those 
+# extraneous messages from stdout and stderr so that when the output files are
+# compared to the expected output, the extra messages will not cause failures in 
+# the tests.  The system messages in the comments below are out of date, meaning
+# I suppose that while the script code to filter messages on the system was 
+# correct correct when last used, the output in the comments doesn't match the
+# script code that follows.  I don't currently have access to any of these 
+# systems to see the current output and the effect of the script code. If using
+# this file in the future, please update the comments to match the scripts in use.

 # Some systems will dump some messages to stdout for various reasons.
 # Remove them from the stdout result file.
 # $1 is the file name of the file to be filtered.
