" 下表中列出了cscope的常用选项：
" -R: 在生成索引文件时，搜索子目录树中的代码
" -b: 只生成索引文件，不进入cscope的界面
" -q: 生成cscope.in.out和cscope.po.out文件，加快cscope的索引速度
" -k: 在生成索引文件时，不搜索/usr/include目录
" -i: 如果保存文件列表的文件名不是cscope.files时，需要加此选项告诉cscope到哪儿
"     去找源文件列表。可以使用”–“，表示由标准输入获得文件列表。
" -Idir: 在-I选项指出的目录中查找头文件
" -u: 扫描所有文件，重新生成交叉索引文件
" -C: 在搜索时忽略大小写
" -Ppath: 在以相对路径表示的文件前加上的path，这样，你不用切换到你数据库文件所
"    在的目录也可以使用它了。
