From 2ac43d981859bda063e7067371c1cf246c7f81b0 Mon Sep 17 00:00:00 2001 From: David Oberhollenzer Date: Sat, 31 Aug 2019 16:59:50 +0200 Subject: Split libsquashfs.a into low seperate libraries The idea is to make libsquashfs.a independend of libfstree.a, so it becomes a general purpose squashfs manipulation library. All the high level glue code for libfstree.a and utilites that are overly specific with to tools are moved to a seperate librarby. This commit makes the first step by moving the stuff with dependencies on libfstree to a seperate library.
