" netrw is the file tree explorer and there's
" a bit of weirdness here because it's a plugin,
" and plugins are loaded after vimrc. so you
" have to define an autocmd that will get called
" after the plugins are loaded

" what this actually does is configure it so that
" netrw opens files in the main editing window
" rather than in its own window, and also focuses
" the cursor onto the main editing window on startup
