# This script builds floppy and CD images. It should be executed each time that
8
# a CORE package has been modified or the build script changed. Before running
9
# it looks for the presence of a /tmp/svardos_repo_changed.flag and stops if
10
# no such flag exists. This flag is expected to be created by an svn
11
# post-commit hook when an important svn change is detected.
