1 # This test is checking to ensure that if a section is removed in the presence
2 # of a segment that the segment maintains its shape and properties and that any
3 # section inside that segment maintains the relative positioning it had in the
4 # segment. Note worthy is that .text3 keeps its offset despite it being
5 # possible to place it after .text when .text2 is removed.
