 \begin{abstract}
     \lebhart{} 是 \colorist{} 文档类系列的成员之一，其名称取自于德文的lebhaft (活泼)，并取了artikel (文章)的前三个字母组合而成。整个 \colorist{} 系列包含用于排版文章的 \colorart{}、\lebhart{} 以及用于排版书的 \colorbook{}、\beaulivre{}。我设计这一系列的初衷是为了撰写草稿与笔记，使之多彩而不缭乱。
 
-    \lebhart{} 支持英文、法文、德文、中文、日文、俄文六种语言，并且同一篇文档中这些语言可以很好地协调。由于采用了自定义字体，需要用 \hologo{XeLaTeX} 或 \hologo{LuaLaTeX} 引擎进行编译。

     \lebhart{} is a member of the \colorist{} class series. Its name is taken from German word ``lebhaft'' (``vividly''), combined with the first three letters of ``artikel'' (``article''). The entire collection includes \colorart{} and \lebhart{} for typesetting articles and \colorbook{} and \beaulivre{} for typesetting books. My original intention in designing this series was to write drafts and notes that look colorful yet not dazzling.
 
-    \lebhart{} supports six languages: English, French, German, Chinese, Japanese and Russian. These languages can be switched seamlessly in a single document. Due to the usage of custom fonts, \lebhart{} requires \hologo{XeLaTeX} or \hologo{LuaLaTeX} to compile.
