しかし、このNvuはCSSファイルをそのまま反映してくれるので、既存のファイルを編集することが便利。
また、そのままFTPとして使えるので、とても簡単!

Nvu (pronounced N-view, for a "new view") is an Open Source project started by Linspire, Inc. Linspire is committed exclusively to bringing Desktop Linux to the masses, and realized that an easy-to-use web authoring system was needed for Linux to continue its expansion to the Desktop. Linspire contributes significant capital, expertise, servers, bandwidth, marketing, and other resources to guarantee the continuation and success of the Nvu project.
Linspire is pleased to have been able to contract with Daniel Glazman from Disruptive Innovations to be the lead developer and maintainer for the Nvu project. Daniel has been the chief architect for Mozilla Composer and brings a tremendous amount of experience and expertise to the Nvu project. Other developers are also encouraged to get involved in this project.
Nvu was started from the Mozilla Composer code base. The Mozilla Internet suite is in the process of being broken up into individual pieces (browser, email, etc.). Nvu will pick up where Composer left off, adding additional features, functionality and ease of use.
