+This library provides an abstraction of buffered output of byte
+streams and several convenience functions to exploit it.  For
+example, it allows to efficiently serialize Haskell values to lazy
+bytestrings with a large average chunk size.  The large average
+chunk size allows to make good use of cache prefetching in later
+processing steps (e.g. compression) and reduces the sytem call
+overhead when writing the resulting lazy bytestring to a file or
+sending it over the network.
+
+This requires ghc and haskell-text.
+
+After uninstalling, run this command to unregister the package from
+the ghc package database:   ghc-pkg recache

+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
