+The goal of Quicksearch is to find the Common Lisp library quickly.  For
+example, if you will find the library about json, just type @code{(qs:?
+'json)} at REPL.
+
+The function @code{quicksearch} searches for Common Lisp projects in
+Quicklisp, Cliki, GitHub and BitBucket, then outputs results in REPL.  The
+function @code{?} is abbreviation wrapper for @code{quicksearch}.")
