+PortInfo(NAME PORT[/PROTOCOL], ...)
+
+=s information
+
+stores named TCP/UDP port information
+
+=io

+None
+
+=d
+
+Lets you use mnemonic names for TCP and UDP ports.  Each argument has the form
+`NAME PORT[/PROTOCOL]', which associates the given PORT/PROTOCOL pair with the
+NAME.  If PROTOCOL is left off, the NAME applies to both TCP and UDP.  For
+example, in a configuration containing
+
+   PortInfo(ssh 22, http 80),
+
+configuration strings can use C<ssh> and C<http> as mnemonics for the port
+numbers 22 and 80, respectively.
+
+PortInfo names are local with respect to compound elements.  That is, names
+created inside a compound element apply only within that compound element and
+its subelements.  For example:
+
+   PortInfo(src 10);
+   compound :: {
+     PortInfo(dst 100);
+     ... -> UDPIPEncap(1.0.0.1, src, 2.0.0.1, dst) -> ...  // OK
+   };
+   ... -> UDPIPEncap(1.0.0.1, src, 2.0.0.1, dst) -> ...
+                                         // error: `dst' undefined
+
+=n
+
+If you do not define a port for a given name, PortInfo will use the default,
+if any.  At user level, PortInfo uses the L<getservbyname(3)> function to look
+up ports by name.  In the kernel, there are no default ports.
+
+PortInfo will parse arguments containing more than one name, as `C<NAME
+PORT/PROTOCOL NAME...>', and comments starting with `C<#>' are ignored.  Thus,
+lines from F</etc/services> can be used verbatim as PortInfo configuration
+arguments.
