How to use the pyflow.demo.cwdDemo.cwdDemo.CwdWorkflow function in pyflow

parentdir=os.path.abspath(os.path.join(cwd,".."))

        self.flowLog("testing pyflow cwd: '%s' parentdir: '%s'" % (cwd,parentdir))

        # task will fail unless pwd == parentdir:
        #
        # test both absolute and relative cwd arguments:
        #
        self.addTask("testAbsCwd","[ $(pwd) == '%s' ]; exit $?" % (parentdir),cwd=parentdir)
        self.addTask("testRelCwd","[ $(pwd) == '%s' ]; exit $?" % (parentdir),cwd="..")



# Instantiate the workflow
#
wflow = CwdWorkflow()

# Run the worklow:
#
retval=wflow.run(mode="local")

sys.exit(retval)
