31# INTRODUCTION
32#
33# This TAP test program mimics the structure and contents of its
34# ATF-based counterpart.  It attempts to represent various test cases
35# in different separate functions and just calls them all from main.

87# If you have read the cp_test.sh counterpart in the atf/ directory, you
88# may think that the sequencing of tests below and the exposed behavior
89# to the user is very similar.  But you'd be wrong.
90#
91# There are two major differences with this and the ATF version. First off,
92# the TAP test doesn't isolate simple_test from force_test, whereas the ATF
93# version does. Secondly, the test script accepts arbitrary command line
94# inputs.
