# 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.
