ANSI Common Lisp  11 Packages 11.1 Package Concepts 11.1.1 Introduction to Packages
11.1.1.1 Package Names and Nicknames
Each package has a name (a string) and perhaps some nicknames
(also strings).
These are assigned when the package is created and can be changed later.
There is a single namespace for packages.
The function find-package translates a package
name or nickname into the associated package.
The function package-name returns the name of a package.
The function package-nicknames returns
a list of all nicknames for a package.
rename-package removes a package's
current name and nicknames and replaces them with new ones
specified by the caller.
