The goal of the license is to serve the eCos user community as a whole. It allows all eCos users to develop
products without paying anybody anything, no matter how many developers are working on the product or
how many units will be shipped. The license also guarantees that the eCos source code will always be freely
available. This applies not only to the core eCos code itself but also to any changes that anybody makes to the
core. In particular, it should prevent any company or individual contributing code to the system and then later
claiming that all eCos users are now guilty of copyright or patent infringements and have to pay royalties. It
should also prevent any company from making some small improvements, calling the result a completely new
system, and releasing this under a new and less generous license.
The license does
not require users to release the source code of any applications that are developed 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

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
