想找个倒数计时的工具。win下，虽然不是一抓一大把，但是总体数量还是在Linux之上的。

Kde环境下有个添加部件的选项，里面的小工具倒是不少，可惜没自己需要的。辗转找到了kde-apps。下载了simplecountdown(http://kde-apps.org/content/show.php/Simple+Countdown?content=121523)

从添加部件--》从本地添加。找不到文件。即便解压后也找不到。说白些，就是无法安装。

从网上找了篇文章，用命令安装成功了。

文章中对于命令行的描述是这样的“

Install via command line

In some cases, installing plasmoid via the above method doesn’t work. The best way is to install via the command line.

plasmapkg -u widget-file-name.plasmoid

If that still doesn’t work, try the following method:

1. Extract the plasmoids to a new folder (right click the plasmoids and select “extract to”) in your home directory. You should see a “contents” folder and a meta.desktop file.

2. Open Konsole.

3. type in the following command:

plasmapkg -i plasmoid-folder-name

where the plasmoid-folder-name is the name of the folder that you extracted the plasmoid to.

If the installation is successful, you should find the plasmoid in your widget library. You can then drag it to the desktop to use it.

It is easy, only if you know the way to do it.

不过我没解压，我直接安装的。但是也成功了。

开始是在IRC里问的，可怜我那蹩脚的英语。最后截图交流:(

还是附上自己的桌面一张。以示纪念
