As a special exception under section 7 of the GNU General Public License,
version 3, the copyright holders give you unlimited permission to use, copy,
modify and distribute the output that Perdix generates, under terms of
your choice. Output means the files Perdix writes for you: exported Python
scripts, SQL queries, recipe files, scikit-learn pipelines and transformed
data. The permission covers the parts of Perdix's own source code that
Perdix copies into that output, such as the helper functions in an
exported script.

This exception does not apply to Perdix itself, or to a modified version
of it, which stay under the GNU Lesser General Public License. If you modify
Perdix, you may extend this exception to your version, but you are not
obliged to do so; if you do not, delete this exception from your version.
