# This file adds config blocks to files that are dependent on a single package
# being present. If for example the 'git' package is present we want content in
# Git's global '/etc/gitconfig' file. If the package is absent that file content
# is removed. If after that the file is empty (i.e. has a size of 0 bytes) the
# file is deleted.
