+# Login access control table.
+# 
+# When someone logs in, the table is scanned for the first entry that
+# matches the (user, host) combination, or, in case of non-networked
+# logins, the first entry that matches the (user, tty) combination.  The
+# permissions field of that table entry determines whether the login will 
+# be accepted or refused.
+# 
+# Format of the login access control table is three fields separated by a
+# ":" character:
+# 
+# 	permission : users : origins
+# 
+# The first field should be a "+" (access granted) or "-" (access denied)
+# character. 
+#
+# The second field should be a list of one or more login names, group
+# names, or ALL (always matches). A pattern of the form user@host is
+# matched when the login name matches the "user" part, and when the
+# "host" part matches the local machine name.
+#
+# The third field should be a list of one or more tty names (for
+# non-networked logins), host names, domain names (begin with "."), host
+# addresses, internet network numbers (end with "."), ALL (always
+# matches) or LOCAL (matches any string that does not contain a "."
+# character).
+#
+# If you run NIS you can use @netgroupname in host or user patterns; this
+# even works for @usergroup@@hostgroup patterns. Weird.
+#
+# The EXCEPT operator makes it possible to write very compact rules.
+#
+# The group file is searched only when a name does not match that of the
+# logged-in user. Only groups are matched in which users are explicitly
+# listed: the program does not look at a user's primary group id value.
