# What license is the code distributed under?

The Monitoring Plugins code is currently distributed using the [GNU General
Public License, Version 3][gpl] (GPLv3).

This is because some C code that we depend upon, from the [Gnulib][gnulib]
project, is distributed under the GPLv3; and therefore, some of our plugins
also need to be GPLv3 licensed.  The team has decided, rather than having a
mixed license, we'll distribute all of the core Monitoring Plugins code under
the GPLv3.

[gpl]: http://www.gnu.org/licenses/gpl.html "GPLv3"
[gnulib]: http://www.gnu.org/software/gnulib/ "Gnulib"
