+rcov.vim allows you to run test unit tests from vim and enter quickfix mode in
+order to jump to uncovered code introduced since the last run.
+
+Installation
+============
+Copy rcov.vim to the appropriate "compiler" directory (typically
+$HOME/.vim/compiler).
+
+Usage
+=====
+
+Setting the reference point
+---------------------------
+rcov's --text-coverage-diff mode compares the current coverage status against
+a previously stored one. It therefore needs that information to be saved
+before you write new code (typically right after you perform a commit) in
+order to have something to compare against.
+
+You can save the current status with the --save option.
+If you're running rcov from Rake, you can do something like
+  rake rcov_units RCOVOPTS="-T --save --rails"
+in order to take the current status as the reference point.
+
+Comparing with a recorded coverage status
+-----------------------------------------
+Type the following in command mode while editing your program:
+   :compiler rcov
+
+rcov.vim assumes rcov can be invoked with a rake task (see README.rake for
+information on how to create it). 
+
+You can then execute rcov and enter quickfix mode by typing
+
+   :make <taskname>
+
+where taskname is the rcov task you want to use; if you didn't override the
+default name in the Rakefile, just
+
+   :make rcov
+
+will do.
+
+vim will then enter quickfix mode, allowing you to jump to the areas that were
+not covered since the last time you saved the coverage data.
