+.IP "wildcards
+Machine names may contain the wildcard characters \fI*\fR and \fI?\fR, or may contain character class lists within [square brackets].
+This can be used to make the \fIexports\fR file more compact; for instance,
+\fI*.cs.foo.edu\fR matches all hosts in the domain
+\fIcs.foo.edu\fR. As these characters also match the dots in a domain
+name, the given pattern will also match all hosts within any subdomain
+of \fIcs.foo.edu\fR.
+.IP "netgroups
+NIS netgroups may be given as
+.IR @group .
+Only the host part of each
+netgroup members is consider in checking for membership. Empty host
+parts or those containing a single dash (\-) are ignored.
+.IP "anonymous
+This is specified by a single
+.I *
+character (not to be confused with the
+.I wildcard
+entry above) and will match all clients.
