适合gnome环境
命令帮助如下：
xml.sh [-dsth] [time] [Directory] [标签]
-d Dir 包含有壁纸的目录
-s time 壁纸静态时间(s),默认1790.0 s
-t time 壁纸切换时间(s),默认2.0 s
-r [itm1 itm2 ...] 根据指定的动态壁纸的标签，删除动态壁纸的信息,默认标签为目录的名字
-h 打印帮助
例如有一文件夹/home/zhang/picture下有若干图片，想把它们添加为动态壁纸，标签设为gnome,可如下执行：
xml.sh -d /home/zhang/picture gnome
指定壁纸静态保持的时间和壁纸间切换的时间
xml.sh -s 100 -t 5 -d /home/zhang/picture gnome
若执行 xml.sh，默认搜索当前目录下的图片并以目录名（非绝对路径）为标签建立动态壁纸信息
删除动态壁纸信息，这需要知道壁纸标签名，可同时指定多个标签
xml.sh -r gnome ...
此脚本只是练习，如有错误，恳请批评指教
