Access2Base is documented at LibreOffice extension & Access2Base.org.
But where do I find documentation for these other libraries:
- Depot,
- Euro,
- FormWizard,
- Gimmicks,
- ImportWizard,
- Tools, and
- WikiEditor?
I don’t believe there is any. I’ve searched a number of times. Even in Pitonyak’s book it states you should look through them for routines you won’t then have to re-write.
I found this related answer which makes some brief references to this stuff.
I also added an answer there to help you get started investigating. It seems that some of this code is linked to the dialogs.
