Just to avoid panic, here is a list of things you *can* do with
Cygwin...
--- if you don't purchase the proprietary-use license ---
[Note that these assume you're still meeting the terms of the GPL,
specifically, you distribute sources with any binaries]
You can...
* give copies to your friends (or enemies, if you like).
* install it on as many computers as you like.
* sell exact copies of what's on sourceware.
* modify it and sell it.
* charge a fee to do custom changes, which you don't tell
anyone else about.
* charge a fee to do changes which you contribute to the
official sources.
* change it and not tell anyone.
* start a new group of cygwin developers, and distribute your
own version publically.
* write programs (apps) that use cygwin.
* use those apps yourself for whatever you want.
* give those apps to friends (or enemies).
* charge a fee for those apps (even though you're distributing
sources too).
* choose an alternate "open source" license for the app (the
cygwin dll remains GPLd).
* do any of the above without asking our permission.
--- if you DO purchase the proprietary-use license ---
* Any of the above
* distribute (sell, give away, whatever) an app without sources.
--- and, for completeness, things you do NOT have to do with cygwin ---
You do NOT have to...
* tell anyone about your changes, if you don't want to.
* give sources to people without binaries (unless you use GPL clause
3b, there are some loopholes in 3b to be aware of), if you don't
want to.
---
I probably missed some, but you get the idea. I hope.
