@ -26,10 +26,7 @@ Tanya consists of the following packages and (top-level) modules:
string, Set, Hash table.
* `conv`: This module provides functions for converting between different
types.
* `encoding`: This package provides tools to work with text encodings.
* `format`: Formatting and conversion functions.
* `functional`: Functions that manipulate other functions and their argument
lists.
* `hash`: Hash algorithms.
* `math`: Arbitrary precision integer and a set of functions.
* `memory`: Tools for manual memory management (allocators, smart pointers).
