Each argument is<br>  either a libspec that identifies a lib, a prefix list that identifies<br>  multiple libs whose names share a common prefix, or a flag that modifies<br>  how all the identified libs are loaded. Use :require in the ns macro<br>  in preference to calling this directly.<br><br>  Libs<br><br>  A 'lib' is a named set of resources in classpath whose contents define a<br>  library of Clojure code. Lib names are symbols and each lib is associated<br>  with a Clojure namespace and a Java package that share its name. A lib's<br>  name also locates its root directory within classpath using Java's<br>  package name to classpath-relative path mapping. All resources in a lib<br>  should be contained in the directory structure under its root directory.<br>  All definitions a lib makes should be in its associated namespace.<br><br>  'require loads a lib by loading its root resource. The root resource path<br>  is derived from the lib name in the following manner:<br>  Consider a lib named by the symbol 'x.y.z; it has the root directory<br>  <classpath>/x/y/, and its root resource is <classpath>/x/y/z.clj. The root<br>  resource should contain code to create the lib's namespace (usually by using<br>  the ns macro) and load any additional lib resources.<br><br>  Libspecs<br><br>  A libspec is a lib name or a vector containing a lib name followed by<br>  options expressed as sequential keywords and arguments.<br><br>  Recognized options:<br>  :as takes a symbol as its argument and makes that symbol an alias to the<br>    lib's namespace in the current namespace.<br>  :refer takes a list of symbols to refer from the namespace or the :all<br>    keyword to bring in all public vars.<br><br>  Prefix Lists<br><br>  It's common for Clojure code to depend on several libs whose names have<br>  the same prefix. When specifying libs, prefix lists can be used to reduce<br>  repetition. A prefix list contains the shared prefix followed by libspecs<br>  with the shared prefix removed from the lib names. After removing the<br>  prefix, the names that remain must not contain any periods.<br><br>  Flags<br><br>  A flag is a keyword.<br>  Recognized flags: :reload, :reload-all, :verbose<br>  :reload forces loading of all the identified libs even if they are<br>    already loaded<br>  :reload-all implies :reload and also forces loading of all libs that the<br>    identified libs directly or indirectly load via require or use<br>  :verbose triggers printing information about each load, alias, and refer<br><br>  Example:<br><br>  The following would load the libraries clojure.zip and clojure.set<br>  abbreviated as 's'.<br><br>  (require '(clojure zip [set :as s]))</p>
