介绍

ePub（Electronic Publication 的缩写，意为：电子出版），是一个自由的开放标准，属于一种可以“自动重新编排”的内容；也就是文字内容可以根据阅读设备的特性，以最适于阅读的方式显示。

EPub 档案内部使用了 XHTML 或 DTBook （一种由 DAISY Consortium 提出的 XML 标准）来展现文字、并以 zip 压缩格式来包裹档案内容。

EPub 格式中包含了数位版权管理（DRM）相关功能可供选用。

Sigil 的运用方式类似于微软办公软件，方便用户上手使用。现在，Sigil可以输入 TXT,HTML 和 EPUB 等文件格式，输出 EPUB 和 SGF(Sigil 原格式)文件格式。支持简体中文界面。
