script makes a typescript of everything printed on your terminal.
It is useful for students who need a hardcopy record of an interactive
session as proof of an assignment, as the typescript file can be
printed out later with lpr(1).
If the argument file is given, script saves all dialogue in file.
If no file name is given, the typescript is saved in the file typescript.
