Personal utilities for Emacs Lisp.

This project is a kind of shelf providing many functions. With a few clearly indicated exceptions, these functions are self-supporting. They do not require any dependency, or to be built/integrated in any specific way. Because "the truly reusable code is the one that you can simply copy-paste".

Many functions are proposed with a 'traditional' implementation, not relying on cl-xxx functions.

A test suite is proposed through file z_tests.el (instructions inside).
