I have been searching for Syntax Highlighter plug-in for Wordpress and Drupal, and decided to install the one available from Alex Gorbatchev. The module makes use of the Syntax Highlighter Javascript Library, and does the job I wanted. In order for Syntax Highlighter plug-in to work, you'll have to install both Javascript library and the module developed for Durpal or Wordpress. Once the module is installed, the syntax for using it is pretty much the same.
