Translations:Preference Packs/30/en

The pre- and post- macro files are standard FreeCAD Python macros, and may contain any commands valid in such a macro. If the pre.FCMacro raises an exception (of any type), the application of the preference pack is cancelled. If the post.FCMacro raises an exception (of any type), the application of the pack is rolled back using the backup taken prior to its application. For example, these macros may be used to query the user for license acceptance, or to verify they are happy with the final state of their system after application.
