For many of the panel-specific options described in InstallerBuilder Options, you can provide Maple procedures.  These procedures run during installation to complete specified tasks, and their results can control the installation.

These procedures need access to data that is in the installer, supplied by a user earlier in the installation process, or supplied by another customized procedure. The ToolboxInstaller[Data] package allows you to save and access this data.

The ToolboxInstaller[Data][Set] command accepts any number of arguments of the form optionN = valueN, where optionN is a string and valueN can be any Maple object. The Set command assigns the value valueN to the string optionN.

The ToolboxInstaller[Data][Get] command accepts any number of arguments of the form optionN, where optionN is a string, and returns the stored value.

You can use Set and Get to create and query custom references, or you can query data automatically set by the installer. The built-in installer data is as follows.

Note: It is not recommended that you use the Set command to overwrite built-in data.
