The bashism used here is 'exec -a', which is used to set argv[0] (the program path) when executing a binary. This trick is necessary, because the program in question looks for files in the directory dirname(argv[0]). Does dash have a way to achieve the same? If not, I'll change the interpreter of this script to /bin/bash.
