How to use the 'optionfile' command line option
The 'optionfile' command line option lets you specify installation options in a separate file. The 'optionfile' option is present on any installer created by InstallBuilder.
The option file should contain one line per option, using the format key=value. You can use any of the options accepted by the installer, for example:
installer-language=es
prefix=/home/bitrock/demo-1.0
mode=xwindow
The 'optionfile' option is very useful for testing environments. You can have several option files where you can specify different installation modes or different settings for the parameters defined in the installers.
