Essentially, Cfetch is a small neofetch-like utility written in C that I made while wanting to learn C. Important note is that this is my first real programming language so obviously not very good.
As of now, it runs on Linux, FreeBSD, NetBSD, OpenBSD, Windows, MacOS X, and Haiku, maybe others.
While there will likely still be some changes made, it is for all intents and purposes mostly complete.
