Jenkins monitors executions of repeated jobs, such as building a software project or jobs run by cron. among those things, current jenkins focuses on the following two jobs:

* building/testing software projects continuously, just like cruisecontrol
or damagecontrol. in a nutshell, jenkins provides an easy-to-use
so-called continuous integration system, making it easier for developers
to integrate changes to the project, and making it easier for users to
obtain a fresh build. the automated, continuous build increases
productivity.
* monitoring executions of externally-run jobs, such as cron jobs and
procmail jobs, even those that are run on a remote machine. for example,
with cron, all you receive is regular e-mails that capture the output,
and it is up to you to look at them diligently and notice when it broke.
jenkins keeps those outputs and makes it easy for you to notice when
something is wrong.
this package provies the jenkins command line interface that supports a wide range of remote interaction with a jenkins instance.
