# GPLv3 §0 ¶1-5

<span class="fitonslide">

<p>

  "Copyright" also means copyright-like laws that apply to other kinds of

works, such as semiconductor masks.

<br/>

<br/>

  "The Program" refers to any copyrightable work licensed under this

License.  Each licensee is addressed as "you".  "Licensees" and

"recipients" may be individuals or organizations.

<br/>

<br/>

To "modify" a work means to copy from or adapt all or part of the work

in a fashion requiring copyright permission, other than the making of an

exact copy.  The resulting work is called a "modified version" of the

earlier work or a work "based on" the earlier work.

<br/>

<br/>

  A "covered work" means either the unmodified Program or a work based

on the Program.

# Binaries (Object Code) are Modifications

+ Software that the computer understands is different than software humans

  read.

+ There is often a process required to modify (and/or translate) the software

  from human-readable

      + This process can be done ahead of time.

+ Separation of source and binary was the first way proprietary software

  companies discovered to subjugate users.

      + GPL uses the fact that binaries are modifications (which are often

        distribution) to prevent that subjugation.

# GPLv2 § 3(a-b)

<p>[GPLv2&sect;]3. You may copy and distribute the Program (or a work based on it,

under Section 2) in object code or executable form under the terms of

Sections 1 and 2 above provided that you also do one of the following:

<br/>

<br/>

a) Accompany it with the complete corresponding machine-readable

source code, which must be distributed under the terms of Sections

1 and 2 above on a medium customarily used for software interchange; or,

<br/>

<br/>

b) Accompany it with a written offer, valid for at least three

years, to give any third party, for a charge no more than your

cost of physically performing source distribution, a complete

machine-readable copy of the corresponding source code, to be

distributed under the terms of Sections 1 and 2 above on a medium

[GPLv3 § ] 6. Conveying Non-Source Forms.

<br/>

<br/>

You may convey a covered work in object code form under the terms

of sections 4 and 5, provided that you also convey the

machine-readable Corresponding Source under the terms of this License,

in one of these ways:

<br/>

<br/>

a) Convey the object code in, or embodied in, a physical product

(including a physical distribution medium), accompanied by the

Corresponding Source fixed on a durable physical medium

customarily used for software interchange.

<br/>

<br/>

b) Convey the object code in, or embodied in, a physical product

(including a physical distribution medium), accompanied by a

written offer, valid for at least three years and valid for as

long as you offer spare parts or customer support for that product

model, to give anyone who possesses the object code either (1) a

copy of the Corresponding Source for all the software in the

product that is covered by this License, on a durable physical

medium customarily used for software interchange, for a price no

more than your reasonable cost of physically performing this

conveying of source, or (2) access to copy the

Corresponding Source from a network server at no charge.

# 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.
