# FIXED:
#
# do not use command output, use built_with_use instead
# this ebuild doesn't directly DEPEND on libpng or jpeg, gd does, see pkg_setup
# for more info
# * bug #12483
#
# '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
#  * bug #24865
#  * the scripts in contrib is not that useful
#    * convertcfg.c: old "host" config has been deprecated for years
#    * daemonchk.cgi: doesn't work for 2.x
#    * htaccess.sample: could be useful
#  * nagios-2 doesn't have RDBMS support anymore
#  * eventhandler/ which is mentioned in the documentation should be installed 
#
# remove "dodoc SAMPLE_FILES", install them into /etc/${PN} instead
# drop dodoc and gunzip sample files, let "make install-config" do the job
# * bug #103945
#
# use doinitd instead of newexe
#
# sed needs to die() if failed
#
# add MY_NAGIOS_* variables, if set correctly, ./configure and 'make
# install' should take care of the permission issue
#
# use econf instead of ./configure

# 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)
