The RTEMS Project tries VERY hard to ensure that any code that 
(1) ships WITH RTEMS and (2) will execute on an embedded target 
in an RTEMS system is licensed in a way that does not place 
a burden on commercial applications. 

The use of the GPL for the tools themselves to compile a 
proprietary application is allowed.  

If you link in other packages, you have to honor their licensing.

Disclaimer: I am not a lawyer.  The above is the intent of the
RTEMS project and if anyone ever sees a case where a piece of
code does not meet these goals, please let us know so we can 
address it.  

We are very careful about honoring software licenses and hope that
everyone else is as well.  These licenses are there to protect the
authors/maintainers/submitters and their work.

Similarly, remember that open source projects in particular need to
be supported to flourish.  Ultimately, even though many projects do
survive on volunteer time, paying for support/training/custom
makes it possible for people to work full time on the project.  Be
an active supporter of open source projects.
