Reusability
OSP

• Other Open Source software provide frameworks
  for interprocess communication and networking
  (Linux, Bind and Sendmail) which allow programs
  such as Ghostview to be coupled with Web browsers
  and servers (Mosaic, Lynx and Apache) to enable
  the rapid initial growth of the World Wide Web.
• Programs such as TeX and Gimp aid creation of Web
  documentation and images. Since most of these
  packages were never intended as Web components,
  the argument could be advanced that the Web
  constitutes the world's most successful example
  of software reuse in the large.
