LibU is a multiplatform C library that comes under a BSD-style license. It includes many interdependent modules for accomplishing several tasks: memory allocation, networking and URI parsing, string manipulation, debugging, and logging in a very compact way, plus many other miscellaneous tasks. It has a small footprint (about 70KB for the default configuration), it is modular, and it has a multiplatform nature, making it an ideal candidate for embedded systems. KLone is an example of such usage.
Jmx4Perl provides an alternate way of accessing Java JEE Server management interfaces that are based on JMX (Java Management Extensions). It is an agent-based approach where a small Web application deployed on the application server provides HTTP/JSON-based access to JMX MBeans registered within the application server. It is set up from a handful of Perl modules, which can be integrated seamlessly in your own programs. It also includes a Nagios plugin, check_jmx4perl, a jmx4perl command line tool for remote JMX queries and operations, and a readline-based JMX shell j4psh, with context sensitive command completion and syntax highlighting.
Osgish is a command line shell for OSGi. It is based on the Readline Library, Jmx4Perl, as the OSGi backend, and Aries JMX as the OSGi Management layer. It is different than other OSGi shells, as it is implemented in pure Perl and provides unique features like wildcard support, context-sensitive command line completion, syntax highlighting, bulk lifecycle operations, advanced query facilities, and remoting via HTTP. It uses jmx4perl and Aries JMX OSGi bundles for accessing the OSGi container remotely.
