LibAST is the Library of Assorted Spiffy Things. It contains many spiffy things, and it is a library. Thus, the ever-so-creative name. LibAST has been previously known as libmej, the Eterm helper library which nobody really understood and certainly never used. The plan is to gradually remove some of the neat stuff from Eterm that could be made generic (things like the theme parsing engine, the command-line options parser, perhaps the event engine, ...) and place it here in the hopes that others will find them useful.

This library consists of a set of functions to manipulate AVL trees. AVL trees are very efficient balanced binary trees, similar to red-black trees. The functions in this library can handle any kind of payload and search key type.

Fcitx is a input method framework with extension support, which provides an interface for entering characters of different scripts in applications using a variety of mapping systems.

This package provides a C library for reading/parsing local and remote bigWig and bigBed files. This library was refurbished to particularly suit to be wrapped by scripting languages by avoiding early bailouts in case of errors.

A macro processor that is used automatically by the GNU C compiler to transform programs before actual compilation.
