string substitution library; profiling libraries

 This is a simple string substitution library that supports "$"-based
 substitution. It is meant to be used when Text.Printf or string concatenation
 would lead to code that is hard to read but when a full blown templating
 system is overkill.
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
