Languages

I defined one option named lang, this option has two alternative values, lang=en (default) or lang=cn . lang=cn will make the caption of figure/table, abstract name, refname etc. Chinese, while lang=en will keep all these stuff English, as the default article class sets. You can use this option as

\documentclass[lang=en]{elegantpaper}
\documentclass{en}{elegantpaper} % both ok
