title: How can I test VIM's Features?
body: <p><em>The features seen with the command ":version" raised my interest.</em></p>
  
  <p>I am particularly interested in the features, such as Ruby, Python and Emacs-tags. I cannot find instructions in the manuals. I found a command "--with-features=huge", after some googling, but it does not show how to really install the features. I have used Vim over a year, so I am rather flabbergasted of the features. I have installed things, such as Taglist. What is the main difference to them?</p>
