The Green Bank Telescope (GBT) is a 100-m diameter antenna with an unblocked aperture and an active surface. It is designed to observe at frequencies from 300 MHz to 100 GHz. Construction of the telescope is now in the final phase - installation of the surface panels - and will be completed in early 2000. The electronics systems for the telescope have been under development and testing in a "Mock-up" which includes the receivers, LO systems, analog filters, and the backends. Upon completion of construction, the telescope will undergo a series of commissioning procedures to prepare for general astronomical observing. We will illustrate the software tools being developed in support of the engineering tests and commissioning requirements of the GBT. These requirements include analysis of holography data, which will be used to measure the initial surface accuracy of the dish. This software is being developed in the AIPS++ programming environment using Glish, a powerful scripting language adopted by the AIPS++ system.
