README file n. Hacker's-eye introduction traditionally included in the top-level directory of a UNIX source distribution,
containing a pointer to more detailed documentation, credits,
miscellaneous revision history, notes, etc. (The file may be named
README, or READ.ME, or rarely ReadMe or readme.txt or some other
variant.) In the Mac and PC worlds, software is not usually
distributed in source form, and the 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".
