The binary file would be in the bin subdirectory of ".cabal" Names that start with a . are hidden files/directories on linux, by the way. So the first line checks if you have "cabal" in your path list. If not, on the 3rd line it supposes your home directory is /home/andrew and adds the cabal binary directory to your path list.
Oh, right. So it's checking whether it's already in the search path before adding it. I would have just added it. ;-) [And by the looks of it, I would have got even that wrong...]
