Hi,

Thank you for your answer, I'm happy to know I got it wrong.
Let me explain what I want to do, and please tell me if it's ok.

I want to develop a businness/financial  software that deals with customers,
invoices, accouting, cash flow, charts , sql database and that sort of
thing.
This software will have nothing to do with Squeak, except it would be built
on top of Squeak.
It would run on a modified version of squeak VM, with all of the development
tools and lot of packages deleted from the image, no sources and no way to
get 'in' the system.
I'm ok for giving all the source of the tools and extensions to the system
and vm I could develop (widgets, printing, tricks, howto, etc) to the Squeak
comunity, but ONLY to the Squeak community.

I don't want to distribute any source with my software, just the exe/image
files, and nothing else.
I don't want to display any special license or copyright mention anywhere in
the software.
I would include a mention and pointers to Squeak in technical documentation,
as we usually do in small letters somewhere near the end of the 3rd part of
the preface with other copyrights mentions.

Is it compatible with SqueakL/IanL and generally speaking with the spirit of
squeak ?
