Smalltalk User Guide : Packaging, unloading, and analyzing code : Simple packaging : Running the packager : Starting Application
Starting Application
The Packager has a Control Panel to set which class starts the packaged image, what code is run to start the packaged image (aka. reduced runtime image) and what the image (aka “output file”) should be called. The browser below allows you to customize this.
For instance, you could change the “output file” to be chooser.icx. Chooser being more indicative of the application and .icx to indicate the outpout file is, in fact, a VA Smalltalk image.
