The Apache License is a permissive free software license, imposing minimal restrictions on the redistribution of covered software. This is in contrast to copyleft licenses like the GPL, which have reciprocity share-alike requirements. The Apache License is named for the Apache Software Foundation, where it originated.
See the Wikipedia article on the Apache License for more information.
