Software distribution

From Wikipedia, the free encyclopedia

A software distribution is a bundle of a specific software (or a collection of multiple, even an entire operating system), already compiled and configured. It is generally the closest thing to a turnkey form of a usually GPL or open source source code for a software. It usually takes the form of either rpm, deb, tgz, msi, exe etc. installer and is downloadable from the Internet. These are also known as a Binary distributions. Examples range from whole operating system distributions to server and interpreter distributions (for example WAMP installers).

They can be either official distributions by the makers of the software, or 3rd party distributions. Notable is the fact that one using such 3rd party distributions will have to turn to the distribution maker for support, the developers of the actual software being distributed usually do not provide support for 3rd party distributions of their software.

[edit] Open Source Distribution Tools

GNU Autotools are widely used for distributions which consist of source files written in C++ and the C programming language, but are not limited to these.

The Python programming language offers a distribution utility called distutils, which requires the creation of a setup.py configuration file.

[edit] Distribution Tools for Mobile Devices

Distribution of software to small mobile devices such as phones, PDAs and other hand-held terminals is a particular challenge due to their ad-hoc connectivity. Some tools that cater to this category of devices are:

[edit] Standard Files

Open source projects typically contain a few standard files that live in the root of the distribution extraction. These files are most commonly named:

  • README - top level documentation overview
  • Changelog - list of changes spanning the life of the project
  • INSTALL - instructions on how to install
  • LICENSE or COPYING - conditions of use and redistribution
  • CREDITS or AUTHORS - attribution for project contributors

Some less frequently used names that you might also see:

  • FAQ - frequently asked questions (and answers)
  • TODO - list of features yet to be implemented
  • BUGS - list of software bugs
  • HACKING - development guide for new participants
  • NEWS - interesting project information, sometimes used in place of the Changelog
