 2 URI Parsing
 *************
 
 A URI consists of several “components”, each having a different meaning.
 For example, the URI
 
      http://www.gnu.org/software/emacs/
 
 specifies the scheme component ‘http’, the hostname component
 ‘www.gnu.org’, and the path component ‘/software/emacs/’.
 
    The format of URIs is specified by RFC 3986.  The ‘url’ library
 provides the Lisp function ‘url-generic-parse-url’, a (mostly)
 standard-compliant URI parser, as well as function ‘url-recreate-url’,
 which converts a parsed URI back into a URI string.
 
  -- Function: url-generic-parse-url uri-string
      This function returns a parsed version of the string URI-STRING.
 
  -- Function: url-recreate-url uri-obj
      Given a parsed URI, this function returns the corresponding URI
      string.
 
    The return value of ‘url-generic-parse-url’, and the argument
 expected by ‘url-recreate-url’, is a “parsed URI”: a CL structure whose
 slots hold the various components of the URI.  the CL Manual
 (cl)Top, for details about CL structures.  Most of the other functions
 in the ‘url’ library act on parsed URIs.
