# This is natively a Debian package; on Debian systems, /etc/ppp/ip-up has
# the following line:
#
# run-parts /etc/ppp/ip-up.d \
#  --arg="$1" --arg="$2" --arg="$3" --arg="$4" --arg="$5" --arg="$6"
#
# It runs every script in /etc/ppp/ip-up.d/, where packages are supposed to add
# them, instead of editing /etc/ppp/ip-up or /etc/ppp/ip-up.d. However, this
# directory does not exist in other GNU/Linux distributions, including Gentoo.
#
# This ebuild creates the directory and the script within, and asks the user to
# call the script directly from /etc/ppp/ip-up. An alternative would be doing it
# the Debian way (run-parts(8) belongs to sys-apps/debianutils), but, while this
# approach would be very elegant, it doesn't really matters, since no other
# Gentoo package will benefit from it.

# /usr/share/doc/vixie-cron-4.1-r8/FEATURES.gz, patched by
# vixie-cron-4.1-gentoo-r4.patch.bz2:
#
# If it exists, the /etc/cron.d/ directory is parsed like the cron
# spool directory, except that the files in it are not user-specific
# and are therefore read with /etc/crontab syntax (the user is
# specified explicitly in the 6th column).
#
# This is not an original vixie-cron feature, but Debian (and Gentoo, and
# everyone else) patched it for this behaviour.
