GHOST and GIAPI: experience using Gemini's new instrument control system framework

The new Gemini High Resolution Optical Spectrograph (GHOST) will be controlled with software developed against the new Gemini software framework - the Gemini Instrument Application Programmer Interface (GIAPI). The developers describe their experience using this framework and compare it to control systems developed for earlier Gemini instruments using the original Gemini Core Instrument Control System (CICS) framework.
