+# The input is 4 separate fields, 0..4. It represents the internal form of a URL, pre-escaping.
+# The result is an escaped string for output.
+#
+# The reason the input is represented as 4 different fields is that the algorithm applies different escaping
+# to each piece.

 # Notes: 
-# - The # character only begins a comment if it is the first character on a line.
