Include path
============

I use vim for C programming a lot. And one the cool features vim has is the
_builtin_ completion. Let's take a look at the most basic vim completion system: 

compl-generic
-------------

> CTRL-N                  Find next match for words that start with the
>                         keyword in front of the cursor, looking in places
>                         specified with the 'complete' option.  The found
>                         keyword is inserted in front of the cursor.

So by pressing, <C-n>, vim will basically search within some places for pattern
that would actually match what you are trying to complete.
This 'complete' option mention that you can get completion from included files,
which sounds pretty good! (it's activated by default)

You just need to set the 'path' variable, to tell vim where to search for
included files:

        " this is my personnal value, feel free to adapt it to your needs 
        path=.,,inc,src,/usr/include,/usr/local/include

And now, type the following in a new buffer:

        #include <stdio.h>

        int main(void)
        {
            pri<C-n>

And you get it completed to "printf", with a mention that it comes from
"/usr/include/stdio.h". That's pretty cool!

Why would you bother with some complex plugin right now, when you have all your
system headers ready for completion?
