   A @dfn{property list} (@dfn{plist} for short) is a list of paired
-elements stored in the property list cell of a symbol.  Each of the
-pairs associates a property name (usually a symbol) with a property or

-symbol, such as its documentation as a variable, the name of the file
-where it was defined, or perhaps even the grammatical class of the
-symbol (representing a word) in a language-understanding system.
