added "bandwidthlimit" option
example.dup example config file for duplicity handler
added trac (http://trac.edgewall.com/) environment handler (thanks Charles Lepple!)
- added configfile option to mysql handler (thanks bonniot!)
- uses /etc/mysql/debian.cnf by default
- now, an empty /etc/backup.d/01.mysql file is all you need
+ added configfile option to mysql handler
+ the default is /etc/mysql/debian.cnf. with this,
+ sqldump doesn't need dbusername. (hotcopy still does).
version 0.5 -- April 12 2005
rdiff handler works when remote sshd has a banner
