Sugar is a free and open source desktop environment designed with the goal of being used by children for interactive learning.〔 Developed as part of the One Laptop per Child (OLPC) project, Sugar was the default interface on OLPC XO-1 laptop computers. The OLPC XO-1.5 and later provided the option of either the Gnome or Sugar interfaces. Sugar is available as a Live CD, as Live USB, a package installable through several Linux distributions,〔 or on Windows and Mac OS through virtualization.〔(【引用サイトリンク】url=http://www.sugarlabs.org/index.php?template=page&page=about_overview )〕 Since May 2008, Sugar has been developed under the umbrella of Sugar Labs, a member project of the Software Freedom Conservancy.〔 Sugar is open-source software under the GNU GPL license〔 and many of Sugar Labs' contributors are volunteers.〔(【引用サイトリンク】title=Sugar commit counts )〕 Unlike most other desktop environments, Sugar does not use the "desktop", "folder" and "window" metaphors. Instead, Sugar's default full-screen activities require users to focus on only one program at a time. Sugar implements a journal which automatically saves the user's running program session and allows him or her to later use an interface to pull up their past works by date, activity used or file type. ==Design principles== "Low floor, no ceiling" is the mantra used by OLPC - and now Sugar Labs - as motivation for the design and development principles. Sugar aims to be a platform suitable for all kinds of creative expression which provides a low floor to the inexperienced, but doesn't impose a ceiling upon more advanced users. The following list, while certainly not comprehensive, provides a starting point for such considerations. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sugar (software)」の詳細全文を読む スポンサード リンク
