 Synopsis:            libpq binding for Haskell
 
-Description:         This binding uses the libpq asynchronous API in
-                     combination with threadWaitRead and
-                     threadWaitWrite to take advantage of the I/O
-                     manager.
+Description:         This is a binding to libpq: the C application
+                     programmer's interface to PostgreSQL. libpq is a
+                     set of library functions that allow client
+                     programs to pass queries to the PostgreSQL
+                     backend server and to receive the results of
+                     these queries.
