-TTMath - a bignum library for C++
+A bignum library for C++
 
 TTMath is a small library which allows one to perform arithmetic operations
-with big unsigned integer, big signed integer and big floating point
-numbers. It provides standard mathematical operations like adding,
-subtracting, multiplying, dividing etc. With the library also goes
-a mathematical parser which helps you solving input formulas read directly
-from a user.

-TTMath is developed under the BSD licence which means that it is free
-for both personal and commercial use.

-The library has some technical limitations:
- * there are only two platforms that are supported: x86 and x86_64,
- * you can use this library only with the C++ programming language.
+TTMath is developed under the BSD licence which means that it is free for
+both personal and commercial use.
 
 The main goal of the library is to allow one to use big values in the same
-way as the standard types like int, float, etc. It does not need to be
-compiled first because the whole library is written as the C++ templates.
-This means only C++ developers can use this library and one thing they have
-to do is to use 'include' directive of the preprocessor. How big the
-values can be is set directly in the source code by the programmer.
