17 ## existing directories but which aren't currently named in the variable are
18 ## added to the left or right (depending on DIR) of VAR. The relative order
19 ## of PATHs added in the same invokation is the same as the order they
20 ## appeared in PATHs: the DIR argument only affects which end of the VAR they
