  *
- * Some examples:
+ * Expexts (part(s) of) an URL as first parameter in form of a string or assoziative array
+ * like parse_url() returns.  Accepts an optional second parameter in the same way as the
+ * first argument.  Accepts an optional third integer parameter, which is a bitmask of
+ * binary or'ed HTTP_URL_* constants.  The optional fourth parameter will be filled
+ * with the results as associative array like parse_url() would return.
+ *
+ * The parts of the second URL will be merged into the first according to the flags argument.
+ * The following flags are recognized:
  * <pre>
- *  url = "page.php"                    => http://www.example.com/current/path/page.php

+ *	- HTTP_URL_REPLACE:        (default) set parts of the second url will replace the parts in the first
+ *	- HTTP_URL_JOIN_PATH:      the path of the second url will be merged into the one of the first
+ *	- HTTP_URL_JOIN_QUERY:     the two querystrings will be merged recursively
+ *	- HTTP_URL_STRIP_USER:     the user part will not appear in the result
+ *	- HTTP_URL_STRIP_PASS:     the password part will not appear in the result
+ *	- HTTP_URL_STRIP_AUTH:     neither the user nor the password part will appear in the result
+ *	- HTTP_URL_STRIP_PORT:     no explicit port will be set in the result
+ *	- HTTP_URL_STRIP_PATH:     the path part will not appear in the result
+ *	- HTTP_URL_STRIP_QUERY:    no query string will be present in the result
+ *	- HTTP_URL_STRIP_FRAGMENT: no fragment will be present in the result
  * </pre>

+ * Example:
+ * <pre>
+ * <?php
