很实用的东东，用命令行的关注。
The gpm is mouse server in Linux.
What it does?
It does the same as any mouse driver and more. It will read mouse events, moves and clicks, and give that information to applications. For instance you can copy and paste text from anywhere on the screen to command line by highlighting the text and pressing middle button. Useful if you want to skip typing of very long file names like openSUSE iso images, for instance.
It has many drivers included, so it will work with almost any mouse on the market.
