 Synopsis:            streamlined html tag parser
 Description:
     Tag-stream is a library for parsing HTML//XML to a token stream.
     It can parse unstructured and malformed HTML from the web.
-    It also provides an Enumeratee which can parse streamline html, which means it consumes constant memory.
+    It provides a Conduit to parse html streamlined, which consumes constant memory.
 
     You can start from the `tests/Tests.hs` module to see what it can do.
