This simple plugin allow you to save session and undofiles in CWD on exit.
Before use session you need create .vim directory or press <F6> and plugin
will create this directory.
When launch vim without arguments and .vim directory exits — session will be
restored.
Enjoy :)
You can install this plugin via pathogen or Vundle. Also, you can just copy vim-project.vim file to ~/.vim/plugin/ directory.
