Apache Geronimo GShell

GShell is a framework for building rich command-line applications. The core of GShell provides the basic features needed by most commands, such as command-line argument/option processing, input/output redirection, preferences handling, ANSI support and a whole lot more.

Size matters when considering a library or framework to be used for the building blocks of an application and for this reason, the core of GShell strives to stay as small as possible, current weighing in at around one megabyte.
