# GPLv3 § 1 ¶ 1, 4-6

<span class="fitonslide">

<p>

The "source code" for a work means the preferred form of the work

for making modifications to it.  "Object code" means any non-source

form of a work.

<br/>

<br/>

The "Corresponding Source" for a work in object code form means all the

source code needed to generate, install, and (for an executable work) run the

object code and to modify the work, including scripts to control those

activities.  However, it does not include the work's System Libraries, or

general-purpose tools or generally available free programs which are used

unmodified in performing those activities but which are not part of the work.

For example, Corresponding Source includes interface definition files

associated with source files for the work, and the source code for shared

libraries and dynamically linked subprograms that the work is specifically

designed to require, such as by intimate data communication or control flow

between those subprograms and other parts of the work.

<br/>

<br/>

The Corresponding Source need not include anything that users

can regenerate automatically from other parts of the Corresponding

Source.

<br/>

<br/>

The Corresponding Source for a work in source code form is that

same work.
