  @param repository
  A <code>File</code> instance for the path to the repository root (the parent
  directory of the .git directory) or a sub-directory in the working tree of the
  repository to run rm against. This argument must represent the absolute path to the
  desired directory as returned by the <code>File.getPath()</code> method. If null is
  passed, a <code>NullPointerException</code> will be thrown.
  @param path
  A single file to remove. The specified path must be relative to the path specified in
  the <code>repository</code> parameter as returned by <code>File.getPath()</code>.
  If null is passed, a <code>NullPointerException</code> will be thrown.
  @exception IOException
  There are many reasons for which an <code>IOException</code> may be thrown.
  Examples include:
  <ul>
  <li>a directory doesn't exist</li>
  <li>access to a file is denied</li>
  <li>a command is not found on the PATH</li>
  </ul>
  @exception JavaGitException
  Thrown when there is an error making the commit.
