GConf is a configuration database system for storing application preferences. It supports default or mandatory settings set by the administrator, and changes to the database are instantly applied to all running applications. It is written for the GNOME desktop but doesn't require it.

GLib is a collection of C data structures and utility functions for the GObject system, main loop implementation, for strings and common data structures dealing with Unicode. This package only binds as much functionality as required to support the packages that wrap libraries that are themselves based on GLib.

Simple time library focusing on simple but powerful and performant API The backbone of the library are the Timeable and Time type classes. Each Timeable instances can be converted to type that has a Time instances, and thus are different representations of current time.

This package comes "Batteries Included" with many useful lenses for the types commonly used from the Haskell Platform, and with tools for automatically generating lenses and isomorphisms for user-supplied data types. The combinators in Control.Lens provide a highly generic toolbox for composing families of getters, folds, isomorphisms, traversals, setters and lenses and their indexed variants.

Haskell's canonical list of tuples syntax for defining maps is not very convenient and also has ambiguous semantics. This package leverages do notation to create a lighter syntax that makes semantics explicit and also allows the option of fail-fast handling of duplicate keys.

This library provides a wrapper to mmap(2) or MapViewOfFile, allowing files or devices to be lazily loaded into memory as strict or lazy ByteStrings, ForeignPtrs or plain Ptrs, using the virtual memory subsystem to do on-demand loading. Modifications are also supported.

This package defines the type class MonadBaseControl, a subset of MonadBase into which generic control operations such as catch can be lifted from IO or any other base monad. Instances are based on monad transformers in MonadTransControl, which includes all standard monad transformers in the transformers library except ContT.

This Haskell package provides ShowQ, ShowFun, and SimpleReflect. * ShowFun gives a Typeable-dependent instance for showing functions as their type. * ShowIO does the same for IO actions. * ShowQ adds SmallCheck & QuickCheck support. * SimpleReflect allows us to literally see how functions 'expand', through appropriate Show magic.

ThreadScope is a graphical viewer for thread profile information generated by the Glasgow Haskell Compiler (GHC). The ThreadScope program allows us to debug the parallel performance of Haskell programs. Using Threadscope we can check to see that work is well balanced across the available processors and spot performance issues relating to garbage collection or poor load balancing.

htable is a lightweight implementation of hash tables in C, greatly inspired by the implementations of spray and red-black trees found in *BSD kernels. To use it, you only need to copy the header file "htable.h" into your project.
