Brut, the Brutal Router for Unix Tools

Brut is a single-file POSIX shell script designed to serve as the front-end executable for Unix command-line programs. It routes to various commands based on the filename and the first argument passed to it, similar to the Git CLI. Brut ensures portability, allowing programs to run on any contemporary Unix system without additional runtime dependencies.

This script encourages a modular approach to shell scripting, breaking programs into small executables and shared library files. By organizing source files according to certain conventions, Brut simplifies the development process, making it easier to manage larger programs and bootstrapping build systems.
