add more examples

Thanks for your efforts!
Maybe you could submit this patch to the gnome-vfs mailing list [1] for review?

The example should use gnome_vfs_make_uri_from_shell_arg instead.

changed example

This patch includes some documentation and hints how to use the example in the
about section and how to make your path in the filesystem absolute.

This example doesn't look right:
/* using input uri as string from commandline */
char* input_uri_string = argv[1];
/* make uri absolute from relative */
if(gnome_vfs_uri_is_local(input_uri)) {
  /* if the uri exists we can open it.. no need for more tests */
  if(gnome_vfs_uri_exists(input_uri))
  {
  /* do somthing with the uri */ 
  } else {
    /* uri is not absolute */
    absolute_uri_string = gnome_vfs_make_uri_from_input_with_dirs
(input_uri_string, GNOME_VFS_MAKE_URI_DIR_CURRENT);
    absolute_uri = gnome_vfs_uri_new(absolute_uri_string);
  }
}

It doesn't even compile (gnome_vfs_uri_is_local(input_uri) will fail because
there is no input_uri variable), and it shouldn't be doing the checking on the
uri at all, just call gnome_vfs_make_uri_from_input_with_dirs() on the supplied
argument. And for the case of an program argument like this it should use
gnome_vfs_make_uri_from_shell_arg(). 

Also, i think the change overempazises the uri part of the vfs. I commited a
much smaller change that just allows the example to take normal unix filenames
as arguments.
