Tentakel is a program for executing the same command on many hosts in parallel using ssh.
Tentakel has the following features:
* Parallel execution of commands on several hosts.
* Format strings that control how the output of the remote commands is about to be displayed and how the output of different hosts should be separated from each other.
* A powerful configuration file that can be used to define groups of hosts. Such groups can contain other groups. Each group can be assigned a remote method, a username and a format string.
* Easy extensibility to allow for different remote methods (currently only ssh and rsh are supported).
