# 使用辦法： news.cgi?forum=分論壇號&max=顯示幾則文章&maxlength=標題長度&display=1&link=顏色16進制語法&vlink=顏色16進制語法&alink=顏色16進制語法
# 例： 在您首頁的適當位置加入以下語句
#      <script src="news.cgi?forum=1&max=10&maxlength=20&link=0000ff&vlink=7f007f&alink=ff0000&mode=topic"></script>
#      這樣就可以在相應位置顯示1號論壇的最新10篇文章，標題長度為 20，顯示發表文章時間，用文章模式查看
#                                                   (display=0 表示不顯示發表文章時間)
#                                                   (mode=view 表示用新聞模式查看)
# link是自訂超連結的顏色，vlink是自訂已瀏覽的超連結的顏色，alink是自訂目前超連結的顏色
#
# 所有參數均可以省略，預設為查看第1個論壇的前10篇文章，標題最多20個字元、顯示時間、用文章模式
