# cli_printActionPreamble -- This function standardizes action
# preamble messages. Action preamble messages provides a confirmation
# message that illustrate what files will be affected in the action.
#
# Generally, actions are applied to parent directories. Each parent
# directory has parallel directories associated. If one parent
# directory is created/deleted, the parallel directories associated do
# need to be created/deleted too.
