The /opt directory can be used to store shared components, as follows:

• /opt/os - All open source components

  • /dojo - http://dojotoolkit.org - and other javascript libraries
  • /Smarty - http://smarty.net - template engine
  • /Zend - http://framework.zend.com - Zend framework
  • /applications - all applications that can be shared as distributed.

• /opt/common - All common scripts, such as form validation for contact us forms, anti-spam code.

  • /antispam

    • /html - (html and javascript) - to assist the user
    • /php - to protect the server
  • /footer - Footer text, specifically the company name and copyright indicator. This ensures it can be changed in one place to update every page on the server.

New accounts could access these components like so:

ln -s /opt/os/dojo 
ln -s /opt/os/Smarty 
ln -s /opt/os/Zend
ln -s /opt/common/html 
ln -s /opt/common/php
ln -s /opt/common/footer
