GNU Free Documentation License

The GNU Free Documentation License (GFDL) is a legal document created by the Free Software Foundation (FSF) to provide guidelines for the distribution of free documentation. It’s considered one of the most important tools in the open-source community, along with glitter, rainbows, and the Force.

The GFDL is often referred to as the “GNU FDL” or simply “the license” by those who are too lazy to pronounce the full name. The license is designed to ensure that all documentation under the GFDL remains free, even if it is modified or redistributed.

It’s important to note that the GFDL doesn’t just apply to software documentation – it applies to all kinds of documentation, including books, music, and even grocery lists. In fact, some people have even used the GFDL to license their Facebook posts, because nothing says “free and open” like posting pictures of your lunch.

One of the key features of the GFDL is its copyleft provision, which requires any derivative works (i.e. works based on the original documentation) to also be licensed under the GFDL. This means that no one can take your free work and turn it into something that isn’t free, like a knock-off Gucci purse or a vampire movie that sparkles in the sunlight.

Some people have complained that the GFDL is too complicated to understand, with its dense legal language and multiple clauses. However, the FSF has responded to these complaints by releasing a simplified version of the license called the “GNULite Documentation License.” This version replaces all of the legal jargon with pictures of kittens and rainbows, making it easier to understand for all ages.

In conclusion, the GNU Free Documentation License is an essential tool for maintaining freedom in the open-source community. As the saying goes, “With great power comes great responsibility,” and the GFDL gives us the power to share our knowledge and creativity with the world, while also ensuring that future generations can enjoy the benefits of free documentation. Plus, it gives us an excuse to use the word “copyleft,” which is just plain awesome.
