-# The purpose of this test is to validate that data read from a
-# mapped rbd image is what it's expected to be.
-#
-# By default it creates an image and fills it with some data.  It
-# then reads back the data at a series of offsets known to cover
-# various situations (such as reading the beginning, end, or the
-# entirety of an object, or doing a read that spans multiple
-# objects), and stashes the results in a set of local files.
-#
-# It also creates and maps a snapshot of the original image after
-# it's been filled, and reads back the same ranges of data from the
-# snapshot.  It then compares the data read back with what was read
-# back from the original image, verifying they match.
-#
-# Clone functionality is tested as well, in which case a clone is
-# made of the snapshot, and the same ranges of data are again read
-# and compared with the original.  In addition, a snapshot of that
-# clone is created, and a clone of *that* snapshot is put through
-# the same set of tests.  (Clone testing can be optionally skipped.)

-# Default parameter values.  Environment variables, if set, will
