<longdescription>
Eina is a multi-platform library that provides optimized data types
and useful tools for projects.

Among its data types, Eina provides efficient implementation of:

 * double linked list with O(1) append and count;

 * double linked inlist (node is built in the data) with O(1) append;

 * stringshare, a pool of read-only strings that are shared in order
   to save memory (no copies!), fast referencing and
   pointer-comparison;

 * hash table with extensible key support, ships by default with
   string, stringshare, pointer and integer hashes by default;

 * array of pointers, with O(1) count and append, configurable step
   growing;

 * red-black tree;

 * sparse matrix;


As for tools, it provides couple of convenience:

 * generic and extensible logging system;

 * easy to use dynamic module loading (on top of dlopen()) that makes
   it easy to change to static/built-in modules;

 * generic safety-checks system covering NULL pointers and other
   incorrect conditions with logging;

 * 'magic' type checking that check and logs if expected magic number
   is incorrect;

 * easy to use and extensible memory allocators (mempools);

 * fixed-point arithmetic;

 * tile splitter and simplifier (merges);

 * generic iterator pattern (how to walk in one direction), just
   implement the given API;

 * generic accessor pattern (how to randomly access items), just
   implement the given API;

 * benchmark helpers.
