former can be applied to individual buffers and the latter to all
buffers.

use *customize* or place the following lines in a suitable init
file:

   (require 'preproc-font-lock)
   (preproc-font-lock-global-mode 1)

Customization:

You can customize this package using the following:

* `preproc-font-lock-preprocessor-background' -- The *face* used to
  highlight the preprocessor directive

* `preproc-font-lock-modes' -- A list of major modes. A buffer is
  highlighted if it's major mode is, or is derived from, a member
  of this list.
