n. By convention, the top-level directory of a UNIX source distribution always contains a file named `README' (or READ.ME, or rarely ReadMe or some other variant), which is a hacker's-eye introduction containing a pointer to more detailed documentation, credits, miscellaneous revision history notes, etc. In the Mac and PC worlds, software is not usually distributed in source form and a README is more likely to contain user-oriented material like last-minute documentation changes, error workarounds, and restrictions. When asked, hackers invariably relate the README convention to the famous scene in Lewis Carroll's `Alice's Adventures In Wonderland' in which Alice confronts magic munchies labeled "Eat Me" and "Drink Me".
