on the modified code, either by including the sources along with the binaries you deliver (or
with any device containing such binaries) or with a written offer to supply the source code to
the general public for three years. It is perhaps most practical for eCos developers to make the
source code available online and inform those who are receiving binaries containing eCos
code, and probably also the eCos maintainers, about the location of the code. See the full text
of the GPL for the most authoritative definition of the obligations.
Although it is not strictly necessary to contribute the modified code back to the eCos open
source project, we are always pleased to receive code contributions and hope that developers
will also be keen to give back in return for what they received from the eCos project
completely free of charge. The eCos maintainers are responsible for deciding whether such
contributions should be applied to the public repository. In addition, a copyright assignment is
required for any significant changes to the core eCos packages.
The result is a royalty-free system with minimal obligations on the part of application
developers. This has resulted in the rapid uptake of eCos. At the same time, eCos is fully open
source with all the benefits that implies in terms of quality and innovation. We believe that this
is a winning combination.

Preamble
The licenses for most software are designed to take away your freedom to share and change it.
By contrast, the GNU General Public License is intended to guarantee your freedom to share
and change free software--to make sure the software is free for all its users. This General
Public License applies to most of the Free Software Foundation's software and to any other
program whose authors commit to using it. (Some other Free Software Foundation software is
covered by the GNU Library General Public License instead.) You can apply it to your
programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public
Licenses are designed to make sure that you have the freedom to distribute copies of free
software (and charge for this service if you wish), that you receive source code or can get it if
you want it, that you can change the software or use pieces of it in new free programs; and that
you know you can do these things.
