GIMP is a multi-platform photo manipulation tool. GIMP is an acronym for GNU Image Manipulation Program. The GIMP is suitable for a variety of image manipulation tasks, including photo retouching, image composition, and image construction. GIMP has many capabilities. It can be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, etc. GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image manipulation procedures to be easily scripted. One of The GIMP's strengths is its free availability from many sources for many operating systems. Most GNU/Linux distributions include The GIMP as a standard application. The GIMP is also available for other operating systems such as Microsoft Windows or Apple's Mac OS X (Darwin).This manual is available online for free at https://www.gimp.org/docs.

The make utility automatically determines which pieces of a large program need to be recompiled, and issues commands to recompile them. This manual describes GNU make, which was implemented by Richard Stallman and Roland McGrath. This book is available as a free PDF from gnu.org.The Make program is indispensable to maintainers of free software systems. The GNU Make manual, written by the program's original authors, is the definitive tutorial. It also includes an introductory chapter for novice users. The Make utility automates the process of compilation; it is especially useful when the source files of large programs change. It is a small program with a lot of power. This book will show you: How to write your own makefiles Make's rule syntax and how to write your own rules How the Make utility can be configured to automatically put binary and source files in the right places. How to use make to create archive files automatically Define, set and use Make's variables How Make uses targets so that you can broaden or narrow Make's recompilation efforts on demand. And much more! This manual provides a complete explanation of Make, both the basics and extended features.

The GNU SASL Manual gives the reader an understanding of the SASL framework and the GNU SASL implementation, and how the GNU SASL library is used in an application. The manual can be used as a reference manual to get just the information needed about any particular interface of the library. Experienced programmers might want to start looking at the examples at the end of the manual, and then only read up those parts of the interface which are unclear.This manual is available online for free at gnu.org.

Most of the GNU Emacs integrated environment is written in the programming language called Emacs Lisp. The code written in this programming language is the software (the sets of instructions) that tell the computer what to do when you give it commands. Emacs is designed so that you can write new code in Emacs Lisp and easily install it as an extension to the editor. This introduction to Emacs Lisp is designed to get you started: to guide you in learning the fundamentals of programming, and more importantly, to show you how you can teach yourself to go further. This manual is available online for free at gnu.org. This manual is printed in grayscale.

Bash is the shell, or command language interpreter, for the gnu operating system. The name is an acronym for the 'Bourne-Again SHell', a pun on Stephen Bourne, the author of the direct ancestor of the current Unix shell sh, which appeared in the Seventh Edition Bell Labs Research version of Unix.Bash is largely compatible with sh and incorporates useful features from the Korn shell ksh and the C shell csh. It is intended to be a conformant implementation of the ieee posix Shell and Tools portion of the ieee posix specification (ieee Standard 1003.1). It offers functional improvements over sh for both interactive and programming use.While the gnu operating system provides other shells, including a version of csh, Bash is the default shell. Like other gnu software, Bash is quite portable. It currently runs on nearly every version of Unix and a few other operating systems.This manual is available online for free at gnu.org.

Briefly, a boot loader is the first software program that runs when a computer starts. It is responsible for loading and transferring control to an operating system kernel software (such as Linux or GNU Mach). The kernel, in turn, initializes the rest of the operating system (e.g. a GNU system).GNU GRUB is a very powerful boot loader, which can load a wide variety of free operating systems, as well as proprietary operating systems with chain-loading. GRUB is designed to address the complexity of booting a personal computer; both the program and this manual are tightly bound to that computer platform, although porting to other platforms may be addressed in the future.One of the important features in GRUB is flexibility; GRUB understands filesystems and kernel executable formats, so you can load an arbitrary operating system the way you like, without recording the physical position of your kernel on the disk. Thus you can load the kernel just by specifying its file name and the drive and partition where the kernel resides.This manual is available online for free at gnu.org.

This manual attempts to be a full description of Emacs Lisp. This manual presumes considerable familiarity with the use of Emacs for editing. Most of the GNU Emacs text editor is written in the programming language called Emacs Lisp. You can write new code in Emacs Lisp and install it as an extension to the editor. However, Emacs Lisp is more than a mere extension language; it is a full computer programming language in its own right. You can use it as you would any other programming language. Generally speaking, the earlier chapters describe features of Emacs Lisp that have counterparts in many programming languages, and later chapters describe features that are peculiar to Emacs Lisp or relate specically to editing.This is edition 3.1 of the GNU Emacs Lisp Reference Manual, corresponding to Emacs version 25.2.This manual is available online for free at gnu.org. This manual is printed in grayscale.

As an OpenStack cloud end user, you can provision your own resources within the limits setby cloud administrators. The examples in this guide show you how to perform tasks by using the following methods: OpenStack dashboard: Use this web-based graphical interface, code named horizon, to view, create, and manage resources. OpenStack command-line clients: Each core OpenStack project has a command-line client that you can use to run simple commands to view, create, and manage resources in a cloud and automate tasks by using scripts.You can modify these examples for your specific use cases.Many chapters in this manual contain links to additional documentation resources. These include additional documentation that is available on the system, and documentation available on the Internet.This book is available for free in many languages and different formats on the suse.com web site.
