# @BLURB: Some functions for cron
# @DESCRIPTION:
# Purpose: The main motivation for this eclass was to simplify
# the jungle known as src_install() in cron ebuilds. Using these
# functions also ensures that permissions are *always* reset,
# preventing the accidental installation of files with wrong perms.
#
# NOTE on defaults: the default settings in the below functions were
# chosen based on the most common setting among cron ebuilds.
