BUG:	There is a typo in the imsurfit code which reads the sections file,
	which can result in some sections specified by the user being ignored
	in the fitting process. Whether or not the code executes correctly
	depends on section specifications themselves since the intended
	test 'if (y2 < y1)' was actually coded as 'if (y2 < x1)'.

STATUS:	The bug is fixed in 2.10.1. There is no workaround.
