**FDL - Fonds de Dotation du Libre - Libre Endowment Fund**

FDL - Libre Endowment Fund is a French endowment fund that supports developers and publishers of Free and Open Source software projects. FDL accepts tax-deductible donations to fund specific feature developments for software deemed of general interest.

FDL works in synergy with its sister non-profit organization, "AWL" (Action pour un Web Libre). FDL focuses on long-term projects, while AWL sponsors short-term initiatives. Both maintain a repository of Free and Open Source software publishers at [afs.one](https://afs.one). Learn more about FDL and AWL at [www.fdl-lef.org](https://www.fdl-lef.org).
