# FIXED:
# this ebuild doesn't directly DEPEND on libpng or jpeg, gd does, see pkg_setup
# for more info
#
# 'USE="jpeg" emerge gd' doesn't work for csh users
#
# user nagios shouldn't have shell
#
# remove duplicated myconf
#
# drop "contrib", if you really need them, write nagios-contrib ebuild
#  * http://bugs.gentoo.org/show_bug.cgi?id=24865
#  * the scripts in contrib is not that useful
#  * nagios-2 doesn't have RDBMS support anymore
#
# remove "dodoc SAMPLE_FILES", install them into /etc/${PN} instead
#
# use doinitd instead of newexe
#
# sed needs to die() if failed

# BUG:
# virtual/httpd or something is needed
# * Nagios should run on any CGI-enabled web server

# TODO:
# proper migration step from older version should be considered
# make sure noweb USE works (it doesn't yet)
# with noweb, /usr/share/nagios/cgi-bin still gets installed
