12 | ## __mdw_addto VAR DIR PATH ... | |
13 | ## | |
14 | ## VAR is the name of a PATH-like environment variable (i.e., one which | |
15 | ## contains a sequence of pathnames separated by colons). DIR is either `l' | |
16 | ## or `r'. The PATHs are pathnames. Those PATHs which correspond to | |
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 | |
21 | ## get added to. | |
