== Why license needed? ==
Many users complains that, without a proper licence they can not use this library.

Hi,
we are considering using a modified version of QExtSerialPort in one of our
projects (Qt Creator, http://qt.gitorious.org/qt-creator).
Would it be possible to add license header information or a license file to the
QExtSerialPort code base? - This would make re-use of the code base easier.
If that is not possible, could we redistribute the source code with BSD-
license headers manually added?
And
I am also considering packaging the software for Debian, but I
couldn't do it yet just because of the license.

Questions:
Can I use qextserialport in a commercial product?
If yes, how?
Compile it in? I guess no.
If I can use it as a library, how should the README be formulated?
Is the "MIT license" from 2008 appropriate?
== Why can we use MIT? ==
Form the history of [http://lists.trolltech.com/qt-interest/2004-12/msg01022.html qt-interest mail list]
* Wayne Roth, the original author of the project, had said that:
the code is in the public domain. Do whatever you like with it. Right
now I have too many other things to do to put any serious time into
fixing it. Trolltech should be aware of this already; they asked
about a license when they offered to host the tarball.
* Stefan Sander, the maintainer of qextserialport on sourceforge, said that
Hello,
My project registration at !SourceForge have been approved.
http://www.sf.net/projects/qextserialport
I thought an initial licence of Public Domain would be best solution.
Someone wrote: - Because its public domain, some could fork it under different licenses -
And from [http://groups.google.com/group/qextserialport/browse_thread/thread/fbcddbfb4a0b5a51?pli=1 this thread] on qesp mail list, we can see that, current maintainers and users agree with a MIT licence.
* Brandon Fosdick,
I would vote for BSD or MIT :)
* Liam Staskawicz,
That works for me - let's call it MIT and go for it :)
And from [[https://groups.google.com/forum/?fromgroups#!topic/qextserialport/P_5TrNHBICE this other thread]] on the same mailing list:
* Michal Policht,
I agree to license.
