# glance anchors and dependency management
#
class glance::deps {
# Setup anchors for install, config and service phases of the module. These
# anchors allow external modules to hook the begin and end of any of these
# phases. Package or service management can also be replaced by ensuring the
# package is absent or turning off service management and having the
# replacement depend on the appropriate anchors. When applicable, end tags
# should be notified so that subscribers can determine if installation,
# config or service state changed and act on that if needed.
