+
+RFC1738: "Uniform Resource Locators (URL)" by T. Berners-Lee, L. Masinter, M.
+McCahill, December 1994
+
+RFC 3986 is considered the current standard and any changes to urlparse module
+should conform to this.  urlparse module is not entirely compliant with this.
+The defacto scenarios of parsing are considered sometimes and for backward
+compatiblity purposes, older RFC uses of parsing are retained. The testcases in
+test_urlparse.py provides a good indicator of parsing behavior.
