classh is yet another wrapper around ssh for running commands on a number of hosts concurrently. It is similar to xCAT, pssh, Cluster ssh, and a gaggle of other utilities. The only pre-requisite for classh is Python 2.4 or later, and no formal installation is required; a copy of the classh.py file is sufficient to run commands. The SSHJobMan class from classh can be used to create custom job management scripts. This class lets you either wait until all output has returned from a batch job or process the results as they become available by incrementally polling the running job. The output, error messages, exit code, and start and completion times of each job are stored in the results. It's been tested on jobs of over 25,000 hosts and handles over 10,000 hosts per hour across a WAN and without noticeable impact on the administrator's host.
Frankly this listing looks like it's a packaging of a bit of website spam. In other words it seems to only be useful for advertising their diet pill site; especially given the "free to use but restricted" categorization --- which presumably prevents the code from being used to deliver other sorts of "tips" or from using this or re-distributing it to link to some other site.
One can easily imagine Freshmeat being inundated with thousands of copy cats which are spamvertisements thinly wrapped in a veneer of installable "code."
Ummm, how does this differ from GNU date?
I have to wonder, given the package's description, what this does that one can't simply accomplish with the following single line of shell scripting:
date -d "$(( $(date +%s) - $EPOCH )) seconds ago" +"$DESIRED_DATE_FORMAT"
Which the stock GNU date command, from coreutils, handles just fine (including for epoch values in the future, which naturally generate a negative number of "seconds ago" --- odd looking to a human, but reasonably handled by the software nonetheless).
