IUSE="apache2 classicui lighttpd perl +web vim-syntax"
# In pkg_postinst(), we change the group of the Nagios configuration
# directory to that of the web server user. It can't belong to both
# apache/lighttpd groups at the same time, so we block this combination
# for our own sanity.
#
# This could be made to work, but we would need a better way to allow
# the web user read-only access to Nagios's configuration directory.
#
REQUIRED_USE="apache2? ( !lighttpd )"
# sys-devel/libtool dependency is bug #401237.
#
# Note, we require one of the apache2 CGI modules:
#
# * mod_cgi
# * mod_cgid
# * mod_fcgid
#
# We just don't care /which/ one. And of course PHP supports both CGI
# (USE=cgi) and FastCGI (USE=fpm). We're pretty lenient with the
# dependencies, and expect the user not to do anything /too/
# stupid. (For example, installing Apache with only FastCGI support, and
# PHP with only CGI support.)
#
# Another annoyance is that the upstream Makefile uses app-arch/unzip to
# extract a snapshot of AngularJS, but that's only needed when USE=web.
