# If NAME is given, this is used instead of <dir> as the name of
# the branding component. This is needed if <dir> is more than
# one level deep, or to rename a component as it gets installed.
#
# If SUBDIRECTORIES are given, they are relative to <dir>, and are
# copied (one level deep) to the install location as well.
