Which looks easier and nicer to you?

NGINX_MODULES_HTTP="access auth_basic autoindex browser charset
fancyindex fastcgi geo gzip limit_req limit_zone map memcached proxy
realip referer rewrite scgi spdy split_clients ssi upstream_check
upstream_ip_hash userid uwsgi"

or:

www-servers/nginx nginx_modules_http_access nginx_modules_http_auth_basic nginx_modules_http_autoindex nginx_modules_http_browser nginx_modules_http_charset nginx_modules_http_fancyindex nginx_modules_http_fastcgi nginx_modules_http_geo nginx_modules_http_gzip nginx_modules_http_limit_req nginx_modules_http_limit_zone nginx_modules_http_map nginx_modules_http_memcached nginx_modules_http_proxy nginx_modules_http_realip nginx_modules_http_referer nginx_modules_http_rewrite nginx_modules_http_scgi nginx_modules_http_spdy nginx_modules_http_split_clients nginx_modules_http_ssi nginx_modules_http_upstream_check nginx_modules_http_upstream_ip_hash nginx_modules_http_userid nginx_modules_http_uwsgi

What is the problem with global flags? Its namespaced and never going to
interfere with other packages. The only difference is the descriptions
are in use.desc instead of use.local.desc, why does that matter?
