 ## Aim
 `fpgen` aims to bring you an easy-to-use framework for stream programming in C++. Generators can be created, manipulated and lazily aggregated at will using a set of simple functions. Iterators over the generator make it easy to iterate over lazy functions.

 ## Requirements
 This project strongly depends on C++20. For an optimal experience, I recommend GCC version 11.2 or greater.  
 For the tests, we rely on Google Test via the Conan package manager, so make sure you have that installed as well.
