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.

• Use, copy and distribute the unmodified source or binary forms of the licensed program
• Use, copy and distribute modified source or binary forms of the licensed program, provided that all distributed copies are accompanied by the license
