universe@259: Welcome to the UAP Common Extensions.
universe@259: 
universe@259: With this library we provide useful data structures and algorithms for common
universe@259: programmatic tasks in the C language. By design the features are divided into
universe@259: modules to minimize the library footprint. Using the build files you can create
universe@259: a static and a shared lib containing all modules, but you may also use the UCX
universe@259: sources in your project and compile specific modules by yourself to further
universe@259: minimize the footprint.
universe@259: 
universe@333: If you want to use this library, you can [download and install](install.html)
universe@259: the recent version.
universe@259: The source code is also available as Mercurial repository [at our site][1] and
universe@259: on [Source Forge][2].
