- Benchmarks are useful not just to compare FLIF to other formats, but also to evaluate modifications in FLIF itself. Test images and benchmark scripts are collected here: https://github.com/FLIF-hub/benchmarks (Shell scripts / Gnuplot)

FLIF is currently licensed under the GNU LGPL v3+. The decoder library libflif_dec is licensed under the Apache 2.0 license.
When the project is more mature, we (Jon Sneyers and Pieter Wuille, the primary/initial authors of FLIF)
may want to release it under an even more permissive or a different Free Software license should that become desirable.
For this reason, we ask contributors (i.e. authors of a pull request) to agree to the Contributor License Agreement (CLA) you can find in the file FLIF-CLA-template.txt in this repository. That allows us to relicense FLIF, including your contributions, if needed.
More precisely, the set of potential outbound licenses that can be considered, are the GPL-Compatible Free Software Licenses as listed on this page: https://gnu.org/licenses/license-list.html#GPLCompatibleLicenses
Please add your signed CLA to http://github.com/jonsneyers/FLIF-CLAs/ (you can find a template in FLIF-CLA-template.txt)
