# info: add web domain
# options: USER DOMAIN [IP] [ALIASES] [PROXY_EXTENSIONS] [RESTART]
#
# The function adds virtual host to a server. In cases when ip is
# undefined in the script, "default" template will be used. The alias of
# www.domain.tld type will be automatically assigned to the domain unless
# "none" is transmited as argument. If ip have associated dns name, this
# domain will also get the alias domain-tpl.$ipname. An alias with the ip
# name is useful during the site testing while dns isn't moved to server yet.
