commit dfaf2c1581e547df831b3171ad47acd27b4ca2af
Author: Martin Schwenke <martin at meltin.net>
Date: Thu Jul 10 14:19:52 2008 +1000
When in verbose mode with -p, each line is prefixed with the node
address/name. To implement this stderr has redirected to stdout -
this doesn't need to be done but is the simplest implementation.
Remove -t option since it doesn't seem to accomplish much but causes
spurious messages to be displayed by ssh. Add explicit -h and --help
options. Make style of usage message consistent with documentation.
Document new features in doc/onnode.1.xml.
