+# Usage:
+#   _combination [-s S] TAG STYLE \
+#     Ki1[:Ni1]=Pi1 Ki2[:Ni2]=Pi2 ... Kim[:Nim]=Pim Kj[:Nj] EXPL...
+#
+#  STYLE should be of the form K1-K2-...-Kn.
+#
+# Example: telnet
+#
+#  Assume an user sets the style `users-hosts-ports' as for the my-accounts
+#  tag:
+#
+#    zstyle ':completion:*:*:telnet:*:my-accounts' users-hosts-ports \
+#      @host0: user1@host1: user2@host2:
+#      @mail-server:{smtp,pop3}
+#      @news-server:nntp
+#      @proxy-server:8000
+# 
+#
+#  `_telnet' completes hosts as:
+#
+#    _combination my-accounts users-hosts-ports \
+#      ${opt_args[-l]:+users=${opt_args[-l]:q}} \
+#      hosts "$expl[@]"
+#
+#  This completes `host1', `host2', `mail-server', `news-server' and
+#  `proxy-server' according to the user given with `-l' if it is exists.
+#  And if it is failed, `_hosts' is called.
+# 
+#  `_telnet' completes ports as:
+#
+#    _combination my-accounts users-hosts-ports \
+#      ${opt_args[-l]:+users=${opt_args[-l]:q}} \
+#      hosts="${line[2]:q}" \
+#      ports "$expl[@]"
+#
+#  This completes `smtp', `pop3', `nntp' and `8000' according to the
+#  host argument --- $line[2] and the user option argument if it is
+#  exists. And if it is failed, `_ports' is called.
+#
+#  `_telnet' completes users for an argument of option `-l' as:
+#
+#    _combination my-accounts users-hosts-ports \
+#      ${line[2]:+hosts="${line[2]:q}"} \
+#      ${line[3]:+ports="${line[3]:q}"} \
+#      users "$expl[@]"
+#
+#  This completes `user1' and `user2' according to the host argument and
+#  the port argument if they are exist. And if it is failed, `_users' is
+#  called.
