摘要

这是 ~/.bashrc文件的一个例子。在 kde-devel 帐户中使用它,可以使编译过程更简单容易。

代码

## A script to setup some needed variables and functions for KDE 4 development.
## This should normally go in the ~/.bashrc file of your kde-devel user, so
## that it is executed when a session for that user is started.
##
## If you don't use a separate user, the first section with the
## environment variables should go into a separate script.
