+=head1 WILDCARDS AND GLOBBING
+
+Neither guestfish nor the underlying guestfs API performs
+wildcard expansion (globbing) by default.  So for example the
+following will not do what you expect:
+
+ rm-rf /home/*
+
+Assuming you don't have a directory literally called C</home/*>
+then the above command will return an error.
+
+To perform wildcard expansion, use the C<glob> command.
+
+ glob rm-rf /home/*
+
+runs C<rm-rf> on each path that matches (ie. potentially running
+the command many times), equivalent to:
+
+ rm-rf /home/jim
+ rm-rf /home/joe
+ rm-rf /home/mary
+
+C<glob> only works on simple guest paths and not on device names.
+
+If you have several parameters, each containing a wildcard, then glob
+will perform a cartesian product.
