Grouper client is a command line utility or java jar for Grouper, LDAP, and custom functions.
It consists of one jar, and any included libraries are in a different package structure
than the original so that they can co-exist with the other libraries.  The entry point is
the class: GrouperClient.  The web service interaction is REST, with generally the non-lite
operations

These are the packages:

The src/ext folder has all external packages in a consistent package structure.

The build script will build the external source with compiling jars, but then when running
they arent needed.

The logging in a refactored commons-logging which will look for the real log4j, and if not
there, will use an internal log4j

The build script will generate a zip for institutions, or for institutions to distribute
with institutional defaults.

The usage doc is configurable per institution, and gives all the commands available
through the client.
