From 20b0d509f67dea802706cd6b80b5e20d14988931 Mon Sep 17 00:00:00 2001 From: David Oberhollenzer Date: Mon, 27 Apr 2020 11:59:02 +0200 Subject: Cleanup directory structure of the binary programs Instead of having the binary programs in randomly named subdirectories, move all of them to a "bin" subdirectory, similar to the utility libraries that have subdirectories within "lib" and give the subdirectories the propper names (e.g. have gensquashfs source in a directory *actually* named "gensquashfs").
