Drupal是一套由PHP书写的程序，为网站提供基本的功能和架构。

Drupal是一个内容管理系统（CMS），它可以方便的使您在网上建立一个可撰写，可管理，可发布文章、图片、文件、影音的系统。它是一个论坛，是一个BLOG，是一个信息组织。It is an extensible platform on which you can build custom modules, and it is a set of programming APIs that allows web developers to create custom web applications very rapidly and efficiently.

Drupal is also a vibrant online community with thousands of enthusiastic people from around the world. This community spans the Drupal.org site, several mailing lists, user groups in various countries, a number of nonprofit organizations, some small companies, and a growing army of freelancers who earn their living partially or completely from using or developing Drupal. The community has events, often coinciding with major conferences, and is an excellent example of massively distributed cooperation.

Drupal是一个新的CMS系统，它虽然没有Manbo流行，也没有XOOPS强大，但却是一个非常易用的内容管理系统，可做为个人或大型网站发布、管理、组织不同内容的平台，包含了广为人知的weblog、论坛、投票、新闻聚合、站内搜索、电子商务等功能。
