A free software license is a notice that grants the recipient of a piece of software extensive rights to modify and redistribute that software. These actions are usually prohibited by copyright law, but the rights-holder (usually the author) of a piece of software can remove these restrictions by accompanying the software with a software license which grants the recipient these rights. Software using such a licence is free software as conferred by the copyright holder. Free software licenses are applied to software in source code as also binary object code form, as the copyright law recognizes both forms.
