Things you can do with Cygwin



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.
