It is a minimal license, composed of only two paragraphs, that normally covers single files rather than entire projects (although it is possible to replace the word "file" with "project" or "software" in the text). Its main purpose is to license minor files that do not need to be covered by the GNU General Public License in GPL-licensed projects.

The SPDX identifier for this license is FSFAP.[3]
