- * @page lic_faq License and F.A.Q.
- * ChibiOS/RT is a <a href="http://www.gnu.org/licenses" target="_top">

- * @section faq Frequently Asked Questions
- * - <b>Is ChibiOS/RT free ?</b><br>
- * Yes, free as both in free beer and freedom.
- * - <b>Can I use it in my commercial embedded product?</b><br>
- * Yes, you just have to advertise that you are using ChibiOS/RT by putting
- * a link to the project somewhere on your web site or documentation.
- * - <b>Am I forced to release the source code of my product?</b><br>
- * The exception to the GPL allows you to use ChibiOS/RT in your commercial
- * application without have to release your source code under certains
- * conditions. See the @ref exception_text under "Approved Interfaces" for
- * details.
- * - <b>What I have to contribute back?</b><br>
- * In general you have to offer changes done on existing files (where
- * allowed) or new developments done using the OS template files. As example:
- * - Ports to new architectures because a new port uses copyrighted OS
- * template files.
- * - New, HAL-style, device drivers because device drivers use copyrighted
- * template files.
- * - Improvements on modifiable OS code as described in the
- * "approved interfaces" section of the @ref exception_text.
- * .
- * - <b>Is the exception applicable to any ChibiOS/RT version ?</b><br>
- * The exception is valid only for ChibiOS/RT releases marked as @e stable.
- * Beta, unstable or development versions are covered by the GPL3 alone
- * because are meant for testing only.
- * - <b>I don't want to be bound by any of the above restriction, is this
- * possible?</b><br>
- * You may contact us about a commercial license.
