NOTE: JPE Builder is still a work-in-progress. It has not been updated in a long while so it may no longer function correctly and may actually create non-working portable launchers. So make backups first.

JPE Builder may be used to create and modify standalone portable launchers that run an application with the JauntePE 0.3.0 runtime. For instance, you should be able to use this utility to quickly convert any existing launchers you have so that they work with the new JauntePE 0.3.0 runtime.

If you have an existing, pre-0.3.0 portable launcher, that you wish to update for use with the 0.3.0 runtime, simply drag-n-drop the launcher, or browse to and select it, and then select Build Portable.

If you have a new application that you wish to run portably through a standalone portable launcher, simply drag-n-drop the application's main executable, or browse to and select it, and then select Build Portable.

Launcher and build settings are available for applying the launched application's icon to the launcher, to store the JauntePE config ini file in the launcher, etc.
