Compliance
This is not a legal notice, so do not treat it as one. This is
intended as "plain English" advice for the average person to ensure
they comply with licenses in this software in the most simple way. It takes
the position of "comply with the MOST restrictive license in this
aggregation and then you will comply with all." If you have any doubts,
please consult the full license COPYING files and a lawyer. Take this
as a rough guide.
The simple advice
Do this and you won't go too wrong.
1. Provide the content of ALL of the COPYING, AUTHORS and licenses/COPYING.*
files as printed material with your product and/or in a dialog (e.g.
an "about" dialog) in your product user interface.
2. Provide a URL from which to be able to download "tar files" with
ALL of the source of EFL exactly as it was when used to compile the
binaries for your product that ships EFL. Keep this URL valid for the
lifetime of the product.
3. Unless you are doing PS3 (PSl1ght) development any libraries or
applications you write that use EFL are yours and you do not need to
make the source available.
4. If you made changes to EFL it would be appreciated if you
interacted with us (see http://www.enlightenment.org ) and provided the
changes you made in patch form BEFORE you ship a product, so they may
be reviewed to see if you have made any mistakes and perhaps have
created problems you do not know of yet.
F.A.Q.
Q. Where is the licensing information?
A. See the COPYING file here and then the COPYING.* files inside the
licenses directory that it references. These are the proper legal
pieces of information you will need.
Q. Do I need to make the source public of libraries or applications that I
build on top of EFL?
A. No, UNLESS you use the escape library. Escape is GPL. This is ONLY
needed for PS3 development, so unless you are doing this, it is not
relevant.
Q. Do I need to provide the source for EFL?
A. Yes. In general you do. If you are shipping any of the binaries or
libraries that are produced, you must provide the EXACT source code
used to build those binaries. So stick to doing this and you'll be fine.
Q. If I have to provide source, how should I do this?
A. The best way is to provide a reference in an "about" dialog in the
product that ships the EFL libraries/tools that gives a URL from
which the source can be downloaded EXACTLY as you used to compile EFL.
You may not simply point to upstream repositories and pass the problem
to someone else. You MUST provide the source exactly as used.
You MAY also provide the source code itself on the product itself
(e.g. on its filesystem) (provide the tar archives of the source), or in
place of a download link if you do not believe you will be able to
maintain that download link for the lifetime of the product.
You MAY also (or instead of the above 2) provide the source on media
(CD, DVD, flash etc.) that accompany the product.
Choose 1 or more of the above methods and you will be fine.
Q. Do I need to reproduce the license information in the COPYING* files?
A. Yes. You must provide these with your product, and just like the
source code, provide them as part of the user interface in full (e.g.
in a dialog), or as files in the filesystem, on actual printed
material (manuals, papers) that accompany the product or in CD, DVD
etc. media.
