file locking; profiling libraries

 This package provides access to platform dependent file locking APIs:
 .
 * Open file descriptor locking on Linux ("Lukko.OFD")
 * BSD-style flock(2) locks on UNIX platforms ("Lukko.FLock")
 * No-op locking, which throws exceptions ("Lukko.NoOp")
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
