description	Type-level programming library
long_description	\
	This library permits performing computations on the type-level.	\
	Type-level functions are implemented using functional		\
	dependencies of multi parameter type classes. To date, Booleans	\
	and Numerals (Naturals and Positives) are supported. With	\
	regard to Numerals, there is support for common arithmetic	\
	operations (addition, substraction, multiplication, division,	\
	exponientation, logarithm, maximum, comparison, GCD) over	\
	natural numbers (using a decimal representation to make		\
	compile-time errors friendlier). Although making use of		\
	type-level computations might seem devious and obfuscated at	\
	first sight, it is indeed useful in practice to implement	\
	lightweight dependent types such us number-parameterized types	\
	(e.g. an array type parameterized by the array's size or a	\
	modular group type Zn parameterized by the modulus).
