#!/bin/bash
# Minimal, standalone rebuild of sxwm with all local patches applied.
#
# Does exactly one thing: clone upstream sxwm, apply every *.patch in this
# directory that install.sh's step_sxwm() applies (same order), build, and
# `sudo make install`. No other install.sh steps (deps, sxbar, dmenu, st,
# configs, ...) run. Useful when you only changed an sxwm patch and want to
# rebuild+install it directly, without the interactive prompts.
#
# Usage: ./rebuild-sxwm.sh
