full text of the GPL (either through the above link, or in the le LICENSE in the BusyBox

tarball), and also read the Frequently Asked Questions about the GPL.

If you distribute GPL-licensed software the license requires that you also distribute the

source code to that GPL-licensed software. If you distribute BusyBox without making the

source code to the version you distribute available, you violate the license terms, and

thus infringe on the copyrights of BusyBox. This requirement applies whether or not you

modied BusyBox; either way the license terms still apply to you.

License enforcement

BusyBox’s copyrights are enforced by the Software Freedom Law Center (you can contact

them at gpl@busybox.net), which “accepts primary responsibility for enforcement of US

copyrights on the software... and coordinates international copyright enforcement efforts

for such works as necessary.” If you distribute BusyBox in a way that doesn’t comply with

the terms of the license BusyBox is distributed under, expect to hear from these guys.

Their entire reason for existing is to do pro-bono legal work for free/open source software

projects. We used to list people who violate the BusyBox license in The Hall of Shame, but

these days we nd it much more effective to hand them over to the lawyers.

Our enforcement efforts are aimed at bringing people into compliance with the BusyBox

license. Open source software is under a different license from proprietary software, but

if you violate that license you’re still a software pirate and the law gives the vendor (us)

some big sticks to play with. We don’t want monetary awards, injunctions, or to generate

bad PR for a company, unless that’s the only way to get somebody that repeatedly ignores

us to comply with the license on our code.

My company wants to include BusyBox into a product. What do we need

to do in order to comply with BusyBox’s license?

First: DON’T PANIC. Complying with BusyBox’s license is easy. Complying with

BusyBox’s license doesn’t cost any money. If, after reading the license and this document

something is not clear to you, please send emails with your questions to the BusyBox

mailing lists. We will expand this document to cover them.

If you are distributing the BusyBox binary, you also have to distribute the corresponding

source code. If you modied the source, you have to distribute the modied source.

The text of the license obliges you to provide source code for binaries you distribute, and

gives you exactly three options for providing source code. These options are spelled out

in section 3 of the LICENSE le in the BusyBox source tarball:

3A) bundle the complete corresponding source with the binary.

3B) bundle a written offer good for three years to provide source upon request (these

days this is often a URL).

3C) point you users at the upstream source (i.e. pass along somebody else’s 3B offer).

Using option 3A, that is, putting exact BusyBox source and .cong le you used to build

the binary on the same medium which you use to ship the binary, is the most bullet-

proof approach to license compliance. If you do that, you can stop reading, your license

obligations have been satised.
