摘要：The open-source movement has been very successful in developing software products such as Linux, Apache, and Sendmail that are now serious competitors to well-established proprietary software. It is attracting a lot of attention not just in the computing community, but also in the media, by academic economists, and most recently, by politicians. In many different countries, there are political initiatives trying to get public support for open source such as direct subsidies to open-source projects, standards for use of open-source software in government agencies, and replacement of some proprietary software with open-source software in schools and universities.
