# Do a bonnie++ create/read/delete run using 8192 files (unless
# BONNIE_KFILES environment variable is set -- note this number
# is multiplied by 1024 by bonnie++).  By default the files are
# created in the same directory, BONNIE_NDIRS specifies a count
# of subdirs to evenly spread files through.  Regular files are
# created by default (BONNIE_FILETYPE=regular), alternatively
# the values "symlinks" and "hardlinks" can be used.
# 
# The script then massages the output into CSV format with the
# human-readable output preceding it as a "comment" (#-prefixed).
