^^^^^^^^^^^^
56+
CMake是一个跨平台的安装（编译）工具，可以用简单的语句来描述所有平台的安装(编译过程)。他能够输出各种各样的makefile或者project文件。使用CMake，能够使程序员从复杂的编译连接过程中解脱出来。它使用一个名为 CMakeLists.txt 的文件来描述构建过程,可以生成标准的构建文件,如 Unix/Linux 的 Makefile 或Windows Visual C++ 的 projects/workspaces 。

cgdb
106+
^^^^^^^^^^^^^^^^^^^^
107+
cgdb可以看作gdb的界面增强版,用来替代gdb的 gdb -tui。cgdb主要功能是在调试时进行代码的同步显示，这无疑增加了调试的方便性，提高了调试效率。界面类似vi，符合unix/linux下开发人员习惯;如果熟悉gdb和vi，几乎可以立即使用cgdb。

htop
182+
^^^^^^^^^^^^^^^^^^^^
183+
htop 是一个 Linux 下的交互式的进程浏览器，可以用来替换Linux下的top命令。
184+
185+
与Linux传统的top相比，htop更加人性化。它可让用户交互式操作，支持颜色主题，可横向或纵向滚动浏览进程列表，并支持鼠标操作。
186+
187+
与top相比，htop有以下优点：
188+
189+
- 可以横向或纵向滚动浏览进程列表，以便看到所有的进程和完整的命令行。
190+
- 在启动上，比top 更快。
191+
- 杀进程时不需要输入进程号。
192+
- htop 支持鼠标操作。
