vim目录树插件，方便阅读查看代码

一个小插件，蛮好用的。插件放到~/.vim/plugin/目录下，如果没有此目录，创建，配置信息填入~/.vimrc，如果没有此文件，创建即可。配置好后按F3显示目录树 配置信息： "useful remap nmap <F3> :NERDTree<CR> "NERD Tree let NERDChristmasTree=1 let NERDTreeAutoCenter=1 let NERDTreeBookmarksFile=$VIM.'\Data\NerdBookmarks.txt' let NERDTreeMouseMode=2 let NERDTreeShowBookmarks=1 let NERDTreeShowFiles=1 let NERDTreeShowHidden=1 let NERDTreeShowLineNumbers=1 let NERDTreeWinPos='left' let NERDTreeWinSize=31 nnoremap f :NERDTreeToggle
