-
- > The following fix to the "host" program serves to increase robustness, eg.
- > core dumping on insufficient arguments is in some cases avoided. Default
- > host is the local host, default query type and class is "any". This is all
- > undocumented so far -- both the manual page and the "usage" string needs to
- > be updated.
