Hi Franz,

As a provider of Revolution add-ons, I'd advise you
- contact Heather Nagey <heather at> for more
information about the RevSelect program
- join the RevInterop group
<> to find
out more about packaging and metadata

Generally, I ship my libraries as a self-contained
stack that people can 'start using' and then
initialize with their license key before they can
actually use the commands and functions.

For instance, the PDF library has the API help
built-in as a substack, as well as a separate substack
with demo scripts. When you open the library stack, it
has the copyright information and buttons to take you
to the demo and documentation substacks.

By the way, congratulations with your project: I can't
help but thinking of how one could use this with
Revolution to create a cross-platform alternative to
the excellent Mac-only Delicious Library.

Anyway, I hope this helped,

Jan Schenkel.
