			== Libraries ==
			Whereas proprietary software packages are sealed boxes, and pride themselves on their seamlessnes (think Adobe Photoshop and the creative "suites"), free software is inherantly all about the fact that it's composed of other pieces. These pieces arrange themselves in complex hierarchies. This orientation toward reuse between projects is reflected in how software is install in many different locations, including places such as "/usr/share" -- the ''share'' referring to the idea that this is a place where different software's could put resources that are common.

			TODO: IMAGE OF a packages file layout

			All software depends on [[Library\|libraries]]. Part of the job of a package manager is to make sure that the software

	gcc -o helloworld helloworld.c		gcc -o helloworld helloworld.c

			The resulting file (in the end called ''helloworld'') can be run from the command line by typing:
			./helloworld

			Hello World!

	In 1985, ~~programmer~~ [[Richard Stallman]] writes the [http://www.gnu.org/gnu/manifesto.html GNU Manifesto], in part in response to his frustrations in how his programming work is controlled. He envisions an entire operating system ~~for programmers~~ to be ~~able~~ to ~~keep control over their work~~. In the Manifesto, he writes:		The C language was designed by Dennis Ritchie the context of the [[UNIX]] operating system in the 1970s. Due to conditions of US law, AT&T, the giant American telecom company that owned UNIX could not charge (large) amounts of money for it and UNIX was practically free for anyone to use. As a result, UNIX was widely used in universities, such as MIT.

			In 1985, [[Richard Stallman]], a programmer at the MIT Artificial Intelligence lab writes the [http://www.gnu.org/gnu/manifesto.html GNU Manifesto], in part in response to his frustrations in how his programming work is controlled and how the way companies own and control software (and it's associated tools) can effectively cut-off a programmer for his or her own work. He envisions an entire operating system, to be called GNU (GNU's Not Unix) designed to be free for all to use. In the Manifesto, he writes:

-In 1985, programmer Richard Stallman writes the [http://www.gnu.org/gnu/manifesto.html GNU Manifesto], in response to his frustrations in how his programming work is controlled.
+Compilation turns a programmer's source code into something a particular computer can perform (an executable).
 <blockquote>
 So far we have an Emacs <b>text editor</b> with Lisp for writing editor commands, a source level <b>debugger</b>, a yacc-compatible <b>parser generator</b>, a <b>linker</b>, and around 35 utilities. A <b>shell</b> (command interpreter) is nearly completed. A new portable optimizing C <b>compiler</b> has compiled itself and may be released this year. An initial <b>kernel</b> exists but many more features are needed to emulate Unix. When the kernel and compiler are finished, it will be possible to distribute a GNU system suitable for program development. We will use TeX as our text formatter, but an nroff is being worked on. We will use the free, portable X Window System as well. After this we will add a portable Common Lisp, an Empire game, a spreadsheet, and hundreds of other things, plus online documentation. We hope to supply, eventually, everything useful that normally comes with a Unix system, and more. ''(bold has been added)''
