# Copyright (C) 2016-2022 Mateusz Viste

#

# This script builds floppy and CD images. It should be executed each time that

# a CORE package has been modified or the build script changed. Before running

# it looks for the presence of a /tmp/svardos_repo_changed.flag and stops if

# no such flag exists. This flag is expected to be created by an svn

# post-commit hook when an important svn change is detected.

#

# usage: ./build.sh outputdir [noclean] > logfile
